So I've seen something similar to my issue posted previously but just in case wanted to report. I've been having an issue in which I have not been able to purchase any upgrades past the first slot, nothing has a price and despite having 500 of all available resources I was unable to purchase anything. I never reset my save data but I did restart my save before the first save came through and that would be the only way I could have possibly reset my save. I tried to find the save file itself but I cant find it on my pc (not your fault I just renamed some things and now I cant find the file) so ima just put this report here and wait for the next patch hoping that it resets my game maybe. (good game btw I dropped a follow and am looking forward to what you have in store.) sorry for the wall
