Not necessarily. I believe that the respawn bug becase a problem with one of the patches. Previously it was possible to keep picking up ammo even when you had 50 pieces already. This was changed and when making that change the respawn bug was not caught. A hack of the exe itself wouldn't necessarily work like the respawn.exe program which just constantly resets a couple of memory locations.

There are a handful of aways to fix the problem:

1. Reset memory locations every so often like respawn.exe.

2. When dealing with loose ammo, there should be a check on whether or not the player in question has 50 pieces of ammo already. However, changing the constant which is used in this comparison might make it possible to pick up more than 50 pieces. I haven't played with this idea but I'd like to when I get a chance.

3. Decrement the number of pieces of ammo a player has when he shoots that piece of ammo.
