I have a big problem with the "SaveGames" folder. The saved .acid files do not appear. Just as a curiosity. I log into the game and I can see my saved game. Does anyone else have this similar situation? Because I had a problem with it. When I downloaded the 3.9 version between May and June, all the backups were preserved. But I was curious after that (end of August, 20th), that the last saved file did not save my backup afterwards. My last save was something above 10K level. The same can be said for version 4.0, 4.1 and 4.2. Something is not right with my computer. Is something missing in it?
I'm not sure what a '.acid' file is. However in my 'SaveGames" folder within the main folder structure of GrowthRPG contains up to 3 saves titled 0-2 as 'Save0.sav'. This you can copy to the new versions as you go. The only thing you have to do is start the new version at least once to create the folder structure.
