Same thing happened to me today, rolled under the north wall of the military base at 022, 119.
AKM with PSO-1, 75rnd mag, rails, and folding stock just vanished.

It looked as if the char was standing up halfway under the wall, then he did some weird pose holding the AKM in a 45degree angle....like one would do in real life when checking if the carbine has a round in the chamber, or when you get a stovepipe jam etc.
