I have LadyAvalon's problem in reverse. That is, in my multi-player game, whenever I load a saved game, my bag of holding still has many items in it that I've sold. In fact, I can sell these items at a store, close that dialog, speak to the storekeeper again & when I open the bag of holding the items have reappeared, and the money I 'earned' selling them is not. It's been a great way to get lots of money!
Yes, I have the patch installed and I don't really want to fix this. I just think it's interesting.
LadyAvalon, I do recommend the patch. It is a good thing. Good luck!
