I was glad the Body Pop bug was gone, until I read the forums and noticed it was back. (That sucks, I remember during my noob days I actually found my first Spirit Shroud Armor...only to be scammed and have it taken away.) Anyway, no big loss there.
Here are what bugs I know, people have used these for scams just so you know. Not sure if you already know them, but if not, good you know now =P. Feel free to add, since these are the only two im aware about, so the more i know, the better.
Cube Bug.
Roll Over
I believe i read this on another forum. Anyway you can do this with a druid or necro, i prefer necros. Go to Act5, and on the top floor, fill it completely with clay golem bodies (by recasting golems over and over). Malah is there incase you run out of mana at any time. You cover both Malah's house and the outside top ledge COMPLETELY with golems, to a point that not even one spec of the ground is visible. Then repeat the same on the second floor (the floor above the chest). It doesn't matter if you accidently get some on the stairs, i've tested and its fine. Then go to a wp in a5 and make a tp, presto, game crashes. Why? From what Im assuming, a TP does NOT appear ontop of a clay golem's dead body. It moves to the next available space. However, you stopped that, you blocked the entire top row AND the second row. It has to appear on a third row where I believe blizzard has no animation for, and therefore, game crashes. Time consuming but fun IMO.
