I encountered a crash while playing the 1.09 update.
So I looked at the debug info and found that it crashed while trying to load the Native Species Extinct event.
Then I took a look inside nativespeciesextinct.txt ant noticed that there are a couple of rogue ) on the OnImplement line:
After Environmentalist and Environmentalist_freq, I removed those and got it working again.
Cheers! : )
PS: I think the formulas are a bit off on that one…
I don’t think this event would make Environmentalists happy. It should be -20%, no?
