Hello, I found a fault on the stairs of the Zelenogorks military towers, I tried to climb them while I was crouching with a gun in my hand and I was totally bug. I was in the act of going up and I was only going to one side, when I got off I could no longer enter the inventory or change weapons, etc. I relog it and came back and when it appeared I experienced the aiming error and the gun fired without pressing the left click.

All this happened in this latest vanilla version of the game
