Same thing happened to me and my buddies back when we would farm Vermi. We got two Ultimates up in the Caustic Caverns and one d-bag went all elevator up into the wall somewhere. The very next run we got vermi to spawn. Where did he go? Elevator'd himself into the same ceiling. Man we were angry.
haha, awesome. I killed a Buzzard once in The Dust and the pilots just stayed there in mid-air. They were alive and shooting down at me with their rifles. I killed them and they fell to the ground. It was really funny.
