I was playing that mold and black magic mission, and in the final battle, the crazy but common lag hit me, so I was zooming around the map. But as I did, my character would blow in and out of proportion incredibly fast and his body parts would stretch out everywhere and fly across the map. It was like what happens to characters in cartridge tilting for the N64.
Here are the couple of screenshots I could take while it was happening, it doesn't do the actual glitch justice but whatever.

Ah, yes, the common packet loss lag.
Typically if you lose your packets, you will start to move out of boundaries. The game engine, however still exists and what happens is, you are technically standing on top of the walls/gates. Perspective wise, it looks more like you are closer to the camera, therefore larger.
Tip? Don't try to lag.
