List of Minor Bugs/Tweaks!

I noticed a little bug whilst playing today.

Total ban on trade unions does not make trade unions members = 0, even after multiple years or election cycles. 3% of the population were still members.

-100% + default value + some other increases means its not -100% total :wink:

Haha yeah that must be it! Take note devs!

Its partially normalized sum, -100% doesn’t mean cancelling something.
Same happens with immigration, private healthcare and schools.

I am reading this! I am just swamped with other stuff, and looking forward to having time to address this…


But wait there’s more!

  1. Overcrowded Prisons don’t decrease health.
  2. Synthetic Meat Research doesn’t decrease farmer membership, increase unemployment, or affect land usage over time.
  3. Welfare Fraud Dept doesn’t make capitalists happier.
  4. Energy Efficiency doesn’t affect the cost of the state energy utility.
  5. Press Freedom, Internet Censorship, and General Media Censorship don’t interact with each other or conflict.
  6. Internet Censorship doesn’t make the leader safer from assassination (less extremist content available online)
  7. Trade Unionists aren’t affected by Labor Day Holiday, only socialists.
  8. Rare Earth Metal Mining doesn’t harm the environment, just environmentalist opinion.
  9. Microchips don’t make the leader safer from assassination (ID cards do tho)
  10. Tear Gas, Rubber Bullets, and Water Cannons don’t help reduce inner city riots or other protests.
  11. Corporations don’t affect charity.
  12. National Service doesn’t affect unemployment, the generational wealth gap, or GDP.
  13. Diversity Quotas don’t affect religious opinion.
  14. Gay Marriage doesn’t affect equality, gender equality, or religious membership.
  15. Selective Schooling is unaffected by whether schools are private or public, and public/private schools are unaffected by it as well.
  16. There’s no way to get deflation AFAIK.
  17. International Fusion Research Project doesn’t interact with the Nuclear Fission policy & visa versa.
  18. Right to Privacy and Mandatory Microchips/Wiretapping can coexist.
  19. Closing Airports Completely doesn’t affect State Airline cost/effect but does affect the Air Travel Tax.
  20. Speed Cameras don’t affect motorist income.
  21. Capitalists don’t care about legalized drugs/alcohol.
  22. Organized Crime is unaffected by drug & alcohol policy.
  23. Very high Game Hunting Restrictions don’t increase crime (from people hunting anyway).
  24. High Foreign Relations doesn’t affect Foreign Interference - high foreign relations would probably make foreign countries less likely to mess with you since they like you, yanno?

  28. The Poor don’t care about the minimum wage policy.
  29. A 0% carbon tax makes capitalists happier than a cancelled carbon tax.

  1. When “The Environment” is maxed, tourism gets a -0.71% modifier.
  2. Technology Backwater is increased by all types of secular vs. religious education, except when maxed (in which case it has no effect). For example, education set to Secular increases Technology Backwater by ~10%.
  3. When exiting a playthrough but not exiting the game and reloading into it, the music soundtrack continues where it left off instead of changing.

48.If you have 100 or more political power on a turn (you can get this if you have 2.0+ on all advisors while in an emergency and immediately after an election), the third digit is off the screen.
49. The cost of nationalizing a utility & then selling it off next turn is profitable at its lowest budget setting - not sure if this is intended or not.
50. State Health Service on its lowest setting increases unemployment by 2.4%.

I’ll throw in, (but take numbered places from you)
-State schools, school vouchers and school tax credits do not impact parent opinion.
-Higher wages decrease productivity (why?)
-No link between poor earnings and poverty.
-The minimum wage impact on poverty should be indirect, making a stop through poor earnings. There are people who are technically paid better than minimum wage, but still impoverished.
-Many of the environmental harms of cars do not have a link to traffic congestion. As a guy who has worked with engines I’ll tell you the emissions are worse at idle than at operating load, even if less fuel is consumed. Lower combustion temperatures lead to messier combustion and therefore dirtier exhaust. Yes, more CO2 is produced by burning more fuel, but every other pollutant is worse at lower temperatures.
-Car emissions limits and other car related environmental policies continue to provide full benefit, even if car usage is drastically reduced (I would suggest they should put a less than 1 multiplier on the harmful effects of cars rather than a direct benefit)
-Capitalist opinion of toll roads likely has a decimal in the wrong place. +23% opinion for maxed out toll roads is on par with -24% opinion for maxed out corporate tax.
-Canadian starting alcohol law is wrong. Most of our provinces have a drinking age of 19, some have it at 18. None have a drinking age of 16.
-Some, but not all mass transit programs directly improve productivity. I would think that people being moved around by mass transit would generally have the same benefit regardless of what exact vehicle they rode in. Perhaps remove these direct benefits and add a negative productivity modifier to traffic congestion? Nobody becomes more productive by riding a train, this is simply fighting off the negative of being stuck in traffic. Obviously this would necessitate a rebalance of productivity.

-Needle exchange should reduce health care demand
-Hospital overcrowding should impact private health care, as people spend money to get around the delays
-Hospital overcrowding should increase doctor strike
-Technology increases health care demand? Why?


-extreme nationalism won’t go away unless you lower patriot membership - getting to 0% unemployment and 0% poverty and 100% education is a huge PITA. I was sitting at 100% patriot membership and barely having extreme nationalism still, b/c I had 1% unemployment and 0% poverty… maybe add in other modifiers like press freedom, censorship, stability, etc?

  • water shortage is unaffected by climate change adaptation

  • adding in country geography modifiers for water shortage would be nice

  • luddite riots have surprisingly-little effect on anything

A few visual bugs with the latest patch… I achieved these by clicking around the happiness/membership/income screens in relatively-quick succession.

Sudden thought: health tax credits & school tax credits should be much more effective if you have a flat tax. The policies’ descriptions say that they’re only effective for those who pay tax in the first place… but if there’s a flat tax, everybody pays tax, so wouldn’t it be more effective?

Minor one: change all instances of NONE to VERY LOW. Reason: lots of streamers & newer players get confused that setting a policy to none does not remove all of its negative effects despite being zero. Changing it to VERY LOW makes it clear it isn’t outright cancelled to newer players.

Its single instance of None, since its part of default slider naming.
So it would be very easy to change None to Minimal for example.


yeah, minimal might do the trick too. Something that makes it clear it isn’t non-existent and is still on the books 'til ya cancel it. I’ve seen two different YouTubers / streamers confused by this so far.

Medium-sized bug with election speeches: you can cycle through the randomly-generated speech effects until you find one you like. You can do this by opening up the speech menu, looking at your options, closing it, and opening it again. The options reset each time it’s opened. So a player could repeatedly close-and-open the speech menu until it generates a result the player likes, then have the speech.

Another speech-related medium-sized bug - if you give a speech, save the game & exit, then reload into the game, you can give another speech on the same turn, provided you have the political capital to do it.

  1. Drug addiction does not have any relation to private healthcare (opioid abuse is much-easier with private doctors using separate databases than one, universal, government-run database monitoring prescription amounts, and bogus luxury “rehab” centers also exist)
  2. Mortgage Tax Relief cost & impact should be relative to the amount of private housing
  3. Immigration Protests can occur when ethnic minorities are also patriots
  4. Ethnic minorities still become a huge amount of voters within 2 terms as the US short of drastic, extreme anti-immigrant measures
  5. mandatory national service, happiness of everyone, & low democracy do not affect immigration
  6. foreign nations bombing (the “foreign nation launches air strikes” event) does not affect immigration
  7. Biofuels do not negatively impact the Environment despite turning more forests into corn farms

Special suggestion as a real-life vegan who thinks the plant-based diets trackers could be revamped:
This non-scientific poll of vegan users of a website was pretty helpful. Why People Go Vegan: 2019 Global Survey Results –

  • the people who go vegan for the environment could be reflected well. The more environmentalists there are, the more popular plant-based diets are. Source: Snapshot: Few Americans Vegetarian or Vegan ( (note that in the US, environmentalists are generally part of the Democratic Party here)
  • many vegans are young people. So membership in Youth could make plant-based diets more popular. Source: Snapshot: Few Americans Vegetarian or Vegan (
  • enhanced animal rights (IE hunting & farming policies) may reduce the amount of plant-based diets, as potential vegans have less reason to feel bad for the animals
  • potential dilemma: how to label almond milk. Dairy producers favor banning plant-based alternatives from using animal-based terminology (like “veggie burger” and “soy milk”) as a way to, allegedly, protect consumers from product confusion. Plant-based product companies counter that it’s more to decrease their market share. See Word ‘milk’ banned for use in branding of plant-based products - News - Farmers Guardian ( for example in the UK.
  • the mad cow disease event could have many more people adopt plant-based diets
  • the impact of hunting policy could be increased/decreased based on the amount of plant-based diets

I guess that there needs to be a sense of universalism in D4?
