Seeing a lot of research cheat issues and it doesn’t look like it’s going to get fixed so here’s a workaround: download a pack file manager, go to your napoleon dir. go into the data folder. right-click the data.pack file and open with the manager you just downloaded. Expand data, expand db, scroll down till you see technologies tables. Click on it and you’ll see a table. edit column “reseach_points_required.” I do 10 cause it seems like a safe number.
I do not recommend this if you are not familiar with modding TW games, and you’ll probably have to start a new game. Also, pretty sure this will disable achievements.
