[PR2 Bug] Hat Attack - Dropped hats do not respawn if players are swimming

[Master Raiden]

Problem: Hats that fall off the level do not respawn if all other players are swimming
Type of Problem: Maybe Server
Expected Behavior: Hats respawn back in the level if they fall too far below the level
Actual Behavior: Hats do not respawn if all other players are swimming

Steps to Reproduce the Problem:
1. Drop a hat off the level
2. Get all other players to swim in water (or in the air if they have Cowboy Hat) before the hat respawns
The hat will not respawn until one of the players stops the swimming motion.
This can be either by standing on a block or exiting the water blocks
