2.Add a Slave Chest of another Player that you dont have access too because of acl and protection setting

Instead: Chest added as slave and original owner of the slave chest cant access it anymore as it is now double protected.

What version of the product are you using?
0.7.2-pre1 on Spigot 1.7.9 Build 1543

Do you have an error log of what happened?
there is no log

Please provide any additional information below.
This also causes "ghost" protected Slaves. As if the original owner of a slave removes the sign (yes he can, no double protection here) the chest still remains a slave for the other Mondo System and the Owner still cant access it. Also still items can bve shelved by the other master chest.
This causes all kind of fails that requier admin assistance and the banks file fills up with ghost chests, as when the sign gets destroyed by the original owner, only his Slave gets removed, but not the one from the other master.
This can be used as form of griefing and to annoy other players and the admins.
