I begin to disassemble this mod, its differently have this grenade is no possibility. As an experiment i deleted
moke_grenade_german_mp2,
smoke_grenade_german_mp,
GASGrenadeallies_mp,
GASGrenadeaxis_mp

and gas grenede STILL work in game, I think it's in scripts who are responsible for this.

I look in _weapons.gsc but not find script responsible for function

This is IWD have all folders and files for grenade but without script for damage
