So you know when you have 2 things in a gun category, say ar2 and smg in #3
you run out of smg ammo, but you can still see the gun in the category, and it says 0 ammo.
when you buy a shaped charge, the charge stays in your 5 category with 0 ammo, and when you buy more charges it gives you SLAM ammo, but you dont get any more charges.
theres also 2 more glitches,
1. if you have, say 5 grenades, it says you have 1 ammo, but you can still throw 5. (happens with shaped charges too)
2.unlimited shaped charges glitch.
-buy 1 charge, use it, and then /dropwep. when you pick it up you get your charge and 1 ammo back.
