Just experienced this today for the first time. Usually I could get my weapon by going prone but not this time. I was laying right on top of it and could not get it. Anyone that works with two primary weapons beware!

I have just discovered this as well but I was on top of the Cherno hospital so I was able to see the entire first floor. Could easily be abused for murders. I imagine this can happen anywhere you go prone while in 1st person perspective.
