Grim Squeaker:

This isn't a level bug, but I'll just post it here.

Anyway, if you're using the bowling ball and someone hits you with an explosion, you'll keep getting set back to the throwing animation, after which the explosion'll hurt you again, after which you get set back to the throwing animation, etc.
It's pretty painful, though I guess it's a good way of not making people use the bowling ball as a weapon.
