I dropped every single item from all my players. Got all the way down to 1/2 fps next to the rowboat before I realized it. Then went and tried to leave again and it still errored on me. Selling as opposed to dropping items might work better, I don't know. The guys earlier said something about selling off stuff then killing the nPC you sold/gave them to. I haven't tried that one.

We lost three days on this bug. And the wife had to go back much farther than me. We have just quit playing becuz losing three days of playtime is discouraging as hell. Most people won't know they have this problem until they get ready to leave.

You can zip up your saves folder and send it to Larian support. Might help us get it fixed if more people report it.
