Sometimes when in multiplayer session i could encounter a bug when rounds being fired with M203 Launcher floats in place where barrel_muzzle (bone where projectile is spawning).

It's happening most likely when i im firing round after round, while having more than 30 rounds stored in vest or backpack.

I can't reproduce that bug in local GameMaster scenario, it only being spotted while multiplayer and what is more - mostly it was happening when servers were full.

Most of players using my Mk19 mod were able to reproduce this bug by simply shooting whole box of mk19 rounds.
