There is an Outhouse / Wooden Toilet on Everon GridRef 057-101 that has a bugged door.
First i thought i found the first "closed", not enterable building on the map cause i couldnt open the door.
I somehow had the idea to shoot open the door by destroying the lock, eventhought that wouldnt be arma typical.
Once the Outhouse "recieved enough damage" the door switched to a damaged stage and flipped open "while still being closed". Basically 180° flipped.
