In "tecnical issue" there are a lot of posts like mine and i have just sent some emails to the divinity support. I hope in a solution quickly...
Well, if you find some time - try my suggestion. It may be that the game cannot write savefiles on disk properly, may be due to some weird writing/access permission set up or may be some issue with FS (partition C:\ is full?) or may be some AV program prevents EoCApp.exe doing any proper writing operation on system drive. It would make sense if you did include a compressed savegame (folder) as well.
