On current BYOND version(513.1542), attempting to dig where you are disallowed (Certain maps, houses without permission, certain tile types) will lock up your client as though stuck waiting for a PVP request. You cannot be invited to parties, move, or do much of anything without having to reconnect, and if you try to PVP challenge someone locked up in this manner, it says you can only send one PVP request at a time.

I don't know if this is something that can even be fixed, but it seemed prudent to bug report it regardless.

This has been corrected.
