Dark Rp No weapons from the box when I puch the "use" button

Hello everybody,

I have a big problem with my darkrp mod.

Everything is ok, the server is running pretty well, but, when I m a drugz dealer, or a gun dealer,

if I spawn a box of shippments, I can t get nothing from it.

I mean, I see the box, and also the number of weapons/drugs inside of it, but when I press E to use and take something. I can just see the effect like if something would go out, but nothing comes :S and also the number stay at the max 10/10.

Plz help me, that s the last thing that I need to finish my server
