On any pvp server when you attempt to steal something you always get the message "You cannot take this item as it is in use.". This happens after meeting all the requirements such as turning off faithful and lawful.
As far as I've seen and heard from other people it only happens when you try to steal from the same kingdom.
It has been broken for a pretty long time.
Steps to reproduce:
1. Meet the requirements to steal by turning off lawful and faithful if you follow a god that doesn't allow it.
2. Turn on stealth. Not sure if this affects stealing or not but either turning it on or not both produces the same error
3. Attempt to pick up any item that has the "steal" option.
4. You will not be able to steal even though you should and will get the message "[19:40:50] You cannot take the *item name* as it is in use.
