A stupid bug in the game corrupted my savegame.
I tried downloading savegames from various places, but the game complains about the version.
I would appreciate if anyone can send me a savegame so I could finally finish this endless, tedious chore of a game whose end I am dying to find out.

Thanks in advance,
Shai

This was extremely helpful, thank you so much

After my save stopped working I searched everywhere for backup saves and found this page. Thanks for posting it, it helped me out too.

Hi, anyone has savegames from chapter four please?
