VaultShop corrupts .sav files

[BahroFan]

For some reason VaultShop is corrupting a number of my .sav files (such as Kadish, city, the AhnySpheres, KveerMOUL, and MystMystV) whenever I open it, regardless if I actually edit anything. The corrupted files have to be deleted before I can ever link to those Ages again. If I try, I get trapped in the Link. (in other words, the game hangs.)
