I got a quest to host a royal guest for awhile.
It was a praetor, and the requirement was double bed, ....
All my rooms allready got royal bed, and when i assign the guest to these royal bed's i got the warning that it doesn't met the requirement for that title.
And i think the check should go away from a specified bed to the comfort rating of the bed.
All double bed requirements now also accept royal beds, so I think it should be already fixed. Thanks for reporting.
