Seconds after exiting a building character will rubber band/teleport back inside the building.
Happens irregularly with most buildings
Occurs very often with the Police Station and ATC towers.
I got stuck for about 5-6 minutes trying to escape this bug at the Police Station in Krasnostav. I would run away in any direction and as soon as I would get about 15-20 metres away from the building I would teleport either back towards it or inside it. Eventually i managed to break away from it by running north east.
Also happened a few times with the single story bar/saloon building.
