You hit the nail on the head, yes across the board. Ran through 300 accounts on f2p worlds, a few had p2p accounts in p2p areas and got that message which caused the bot to constantly keep trying the same account to the same error. I eventually just remove those from the list since they clearly work but just thought it was worth mentioning or adding a grouping to.
 
You may also want the "this account is suspected stolen" message which means the account is active but needs a new password.  

Thanks for raising this. 
I'm just going to try and break down your message so I get a better understanding of the issue:
It does not handle F2P world checks on P2P accounts in P2P areas though Do you mean that is a P2P acc has the login message that you can't log into this world as you are standing in a P2P area, it then breaks? It gets in an endless loop of checking the same account and getting the same response. What triggers this? Is this when it hits the response above?
