Some items I picked up after dropping the fireaxe (as both videos {with fireaxe and SGK-5} were back to back without logging out) disappeared after logging back in. In the second video you can see I had a baseball bat and a gas mask. These items were found after dropping the fireaxe but before dropping the SGK-5 and before I logged out, and they both disappeared from my inventory when I logged back in, and the fireaxe and SGK-5 reappeared.
