I was in Novodmitrovsk, and found a mosin and a long range scope. I went into the woods to change my weapons up as I was carrying a SKS also. I went to check to see if anyone was around, I noticed that the long range scope was missing. I checked around to see if I had dropped it, but it was no where to be found, so I just went on my business. I climbed to the top of Town hall, and on the way down I ran into two bandits. I got in to a fire fight with them, and out of no where, my long range scope came back to my gun, and I ended up getting killed as I could not see.
So I guess the bug is my Long range scope, just going missing, and then re-appearing on the gun.
