What were you doing before bug occurred: Joined game (I was imprisoned before and left, appeared in jail cell, someone came by and broke us (there was some else) out, however I couldn’t leave, the invisible walls were still their and unbreakable.
This bug probably happens because there’s an invisible wall around the cell to prevent you from escaping (with cuffs), so the only way to get out is to destroy the cell enough until the whole thing breaks (like how you can break a whole house after enough damage in a town).
