Weapon Malfunction

I m having issues with added weapons like the nuke launcher from the official nuke pack and any air strikes it just shoots the rocket/bomb and it dies it doesn’t shoot off and the only way to detonate it is by manually pressing the use key on it and same with smoke grenades ect from the realistic CSS weapons it throws nothing and i don’t know whats wrong and its annoying

Plz help

New update it also appers only the orignal rpg u start with works
