Camo clothes deleted my backpack

[damule 6]

So thats basically it, i found camo clothes yesterday, and when i tried them on, they deleted my backpack, replacing it for a normal patrol backpack. I had the biggest one, and when i put the clothes on i went through the floor for 1 second, and when i "spawned" with the clothes, i didnt had my backpack... It didnt delete everything in it, just the "extra" slots i was supposed to have.

That's a known bug, always drop your backpack first
