I was having a really good game after a couple losses; had a few kills, got the safe, and was on my way out, when I thought "maybe I should try get the crate? "
So I did, but I got stuck in a prone position. I killed a guy who tried opening it, so his crate was right next to the supply crate. I had done my business, but I couldn't get up. Other players didn't seem to be able to shoot be though, but I could shoot them.
At last, I died to the storm. That was a real let-down.
