I am very sorry if this topic already exists but I haven’t seen any of it.
Problem is, after the Sedan in the beginning of the game I successfully researched some things without any problem. Now I want to start research for a new car design (SUV) and the button is NOT greyed out so I can obvisiously start it, but as I resume at normal game speed the RnD symbol highlights red and they don’t work at all. I found no prerequisites for the design research, so what’s wrong?
Car designs require Design Studios, not research offices. Its a different facility you place that generates points to research new car designs! The design studio itself will need to be researched using the normal method.
