I'll give you another progress report in a few hours.
I'm running it on a skiller with cakes. It runs extremely well, even better than it did on my main, although I just ran it for a couple ours on him.
Just putting it out there. For some reason, if I choose to kill more than 1 wintertodt per inventory, it WILL get the in-and-out door glitch. Only seems to happen when you mess with that setting.
I've managed to do three 6 hour runs in the past week. There's nothing wrong with your script, @Cloud just needs to work on the mouse issue. The spastic menu selection slows the scripts down a fair bit.
