There's another way in there.Danni122112 or someone else felt funny: Sometimes loot chests appear in impossible to reach locations.
There's a button on the other side of the door, and you CAN hit it from inside. Also, Danni did not build this, I did.Good job Danni122112 now I'm trapped - no button or anything to open jail.
Now you have to manually change my location as I don't know when you or other staff will be here.
Edit: Button was added few hours later to those cells and I could finish quests now.
This button was added lol, maybe someone removed it by accident when I was trapped here, but it got fixed few hours later.There's a button on the other side of the door, and you CAN hit it from inside. Also, Danni did not build this, I did.
