The performance for this server seems to have degraded on the time of this report. Infected are very slow in their path and actions at the well take longer to cancel action after clicking cancel action.
Keep in mind this was 10 minutes before the official restart (official restart being 12 o'clock european time and the official restart being 5 minutes after this report was created).
Server crashed 16 minutes after official restart, character inventory and stats rolled back to last logout.
After official restart and server crash, server is still poor performance as above stated.

I noticed after the official server restart SOME doors needed two clicks to open or close (town was rogovo), the icon would change on first click but the door would not move, on some occasions the icon would change and the sound would play but the door would not move, on second click the door would move. Seemed to be mostly the exterior doors or first door you interact with of a house, some interior doors have same issue. This caused a zombie to walk through a door on my screen.

Jitters of lag on movement (already known by devs).

Crash on game exit (already known by devs).
