Ok so I wanted to vault a fence double carrying, it dropped the gun from my hands to the floor and I could not put anything in my hands, at the same second I see a guy run past me ("luckily" he did not see me), so I quickly had to log out and log back in to have access to my hands, 5 seconds later I find the guy, tap fire and get the sticky trigger bug and I loose control of the gun, at this point he hits me and I think I am going to die, "luckily" he goes unconscious and I end him.
Summary:
This was a very frustrating occurance for me, first the need to relog at the point of encountering a player, and secondly the sticky trigger made me more frustrated. These were the two bugs I encountered so far while PVP'ing on 0.57, and it was only the first encounter I have had on this patch. All I can say is that I was "lucky".
