I'm going to dive into the logs and see if I can find any common errors. I'm surprised that the save problems are sporadic. I would think that they would be consistent and easy to reproduce.

Also, I've upped the chance of finding some of the rarer items, like quest items, from three to five percent, so hopefully that will make the game a little more fluid and enjoyable. If you're currently playing, you'll need to save and exit(hopefully the save will behave) and reload your character to pick up the new version of the code.
