The 2 Story Building with a Jail cell to the right of the entrance and 2 rooms at the back, one down stairs and one upstairs.
Next to the bottom room players can glitch through the wall to hide in the unreachable part of the building. They can see out and use it to unfairly ambush players. They also can not be damaged while inside it.
I believe it affects this building everywhere this building is. North East Airfield is where I have experienced this multiple times.
