This also aims for the fix that the player still gets damaged while in debug. It looks like that allowDamage gets lifted when it should not. fn_exitSwim set too early the damage true which can be a problem. Ive decided to remove the handled damage from fn_exitSwim and set allowDamage always false before we enter this function.
This needs intensive testing to be sure it works without any new problems.
Thx to ndavalos and iben.
