I was playing for a while and everything seemed smooth.
Until I ran into a player in the Gorka Police station. He was aiming at me with his pistol as I was entering the room he was waiting in.

In panic I shot at him with my pump action shotgun.
The shot connected and I saw blood popping up but he didn't move. I immediately pressed R to cycle my last round since I only had 2 bullets in total but nothing happened. I was confused for a second until the red message appeared telling me I was losing connection.
I thought I crashed the server until the message disappeared again and massive lag kicked in and teleported my character 2 rooms back. I saw a bunch of players losing connection in the server message log.

As I was running back to the room where I shot at the player my character movement started to stutter as if the server kept correcting my players position. I was still able to somewhat move around.
When I saw the player again he was standing, pulling out his shouldered gun (similar to when people log back in but that was unlikely as barely 10 seconds passed since the server seemingly crashed).
I kinda regret taking advantage of the situation but I shot him in the head with my pistol without second thought. He dropped down immediately. No noticable desync.
When I checked my shotgun I noticed it still had 2 buckshots chambered. Also I assumed his jacked to be ruined from my first shot but it was only damaged with some prestine items inside. As if I never ran into the player before the lag and shot at him in the first place.

The stuttery movement never stopped so I decided to log off an report the issue.
