Honestly, I hadn't run this since, well, forever. I just started it up again, and I can't get it to fail. I even moved to the area where the wood hut is. I ran up the stairs and down. I've looted probably 20 things now; I need to dump items actually. lol.
Anyhow, I can't imaging what's different with your setup at this point. Things are running smoothly here.
