So I just ran into this issue, and thought I'd post in case anyone else sees the same thing.
I was playing a game last night, saved and it crashed to desktop, no error, no nothing. NO surprise, that save is corrupted and attempting to load crashes the game. However, I found that if I started a new game, and attempted to save, it would crash to desktop without any errors still. Uninstalled/reinstalled (steam), no change. So went through and deleted the known corrupted savegame, and now everything works correcty again.
Not sure if this is a side affect of the fix that PetroGlyph is working on, or another issue entirely, but thought I'd post in case anyone was seeing the same issue.
