4.4 Every char must have only one type of ID equipped and they must play to that ID. In cases where these restrictions and allowances conflict with the server rules, the ID overrides the rules
In which case, can you be more specific as to what part here is needed to be fixing. The rule covers a LOT of things (also due to the admins trying to make the rules more 'simple' in writting but not really changing anything. Just wording).
But anyway , can you please be more specific and maybe give an example of something that went wrong?
