I haven't done any gardening since reading about the bugs, but I've been getting a similar micro-managing bug with my mailbox. I almost always use a dog to hunt for gems and metals to make money. However, now when my sim goes to the mailbox to send a bunch of them off to be smelted or cut, she'll only do one, and then reset to about 2-3 feet from the mailbox, queue completely empty. I don't have any trouble telling her to get mail or pay bills, just when she goes to send something. I had this in the game I was playing this weekend (which I can't remember if I started before or after I installed the patch). I also created a new game when I downloaded Supernatural, thinking maybe it would go away when starting a new game. Same problem as before.
Is anyone else having this problem? Any ideas on how to fix it? I've tried ResetSim a couple of times in both games, and no go. Also, how does one go about resetting a world?
