If you are already trapped then it is possible to escape by clicking 'attack' on an npc on the opposite side of the fence, or by clicking 'follow' on a player on the opposite side of the fence. If you still can't get out then wait until monday when the builders are coming in to remove that fence.

We apologise for this bug, it will be fixed on monday. Anyone trying to get other players trapped in that space will be BANNED for bug abuse.
