there is an old expression: A patient is talking to his doctor, patient: "Doctor, it hurts when I go like this" (he does an odd movement with his arm) the doctor studies it for a moment, and then replies: "Don't go like that"
In other words, this seems to be a rather unobtrusive bug. SoA is a HUGE game, and though the programmers did a great job, it is very quirky. Small bugs pop up all the time. I wouldn't lose too much sleep over it. As long as it remains a relatively minor bug and only stops you from sleeping in the docks, I would recomend simply taking your inn-business elsewhere. Don't worry about it, its just not worth the headache
