Hello!
As in title, my weapon got bugged.
I was using my M4 for a long time. Two days ago I had problem with dragging items to my inventory, so i tried logging out and logging in again. After that inventory was working well, normally. But I found out, that magazine is detached from my M4. Before logging out I didn't use this weapon, even didn't reload. Since this happened, I cannot attach any magazine to this weapon, only one bullet in a chamber. I gave it to my mates, but they have the same issue, but only with this one, specified weapon. I have no idea, what can be a problem and why this even happened, but now this M4 is useless and this is not so common to find :(
This is first time this happened. Probably you won't be able to help me with my M4, but maybe it will be possible to prevent this bug to happend in the future :D

Thanks in advanced for all info and have a nice day :)
