Playing this game has been fun especially with my friend until I realized that both of our characters on separate accounts were gone. Spent countless hours trying to figure out what happened and gave up... until it happened again and then I realized it was because of programs that clean up your PC, one i know of for sure is avast. When I went to disable avast form deleting the files or changing them it kept doing it anyway. I tried making a copy of the game files in case it deleted them again, but sadly it didn't work as well. Don't want to stop cleaning my PC just to play this game and cant say I will play it again until this is changed due to constant progression lost. Would be much easier to have progress saved in a different way. (Ex. like the cloud)
