Bug with equipped guns

Tried to play SnD today.

I have AK47+DE silver equipped in bag 1

Bag 2 had M4A1-Bandage and de -rusty

Other 5 i didnt try..

I played 2 rounds with weapons fromn first bag.Then i desided to play with weapons in bag 2.On spawn I pressed B+2 saw Bandage.And weapon in my hand was MicroGalil..

And after 1 shot i got 31:0 error and found myself in channel lobby

I tried again and equipped CBQR-Ap in bag 2..Same result..

I try to make screens now....
