I am also having the issue were the game just keeps saving forever. I am no game programmer or anything, but could the issue here being that people just don't have enough RAM for this? As stated above from Monarch, both him and his friend don't have issues with 8GB. I on the other hand with 4 cant save the game, yet the game run completely smooth on the settings on put it on.

Maybe the problem with saving is how much of the world is loaded at once (I assume it is a lot the furthest I've gotten is a little bit in the graveyard after the town) and there are no (real) loading screens before or after, so maybe with the lack of RAM people have a problem with saving all of this massive world at once? I could also be completely wrong, this is just a guess.
