I feel like there are more, but I can remember at least two fixes I'm responsible for:

* Way back when, there was a quest in...uh...that area with Durin. You had to do something with some bread and an oven. Since the bread item involved in a quest it was somehow special. You could eat it and the item didn't disappear, but it still made you full. So you could just carry around one of these things and never go hungry.

* With Kasir I figured out I could spam up sleeping disarm by either trying to sleeping disarm a mob that wasn't wielding a weapon, or possibly one that was wielding a cursed weapon. No lag, mob didn't wake.
