This thread brings up an interesting situation:
I "lost"
two volleyballs during one match a while ago and we had to wait for the AD to get two new ones out of the bags and inflate them. The reason we lost the original balls was the nails in the ceiling of the old gym. Both times (game 1 and game 3) the ball was hit into the ceiling. As soon as the ball hit a nail (multiple nails were protruding from the ceiling) the ball popped and went flat.
The question I had was this: How would you call this if the team that hit the ball still could legally play the ball and the ball went flat, making it unhittable?
This was the case only once of these two hits. I called a replay, which only seemed fair. The first time the ball popped, we said, "that's a first, it'll never happen again!". We were wrong!
