Lordsport bug (unplayable)

[Daswin]

Playing on 4.1 and lords mainly from westerlands and north get stuck when going near lordsport in iron islands. When they want to go home they just keep traveling back and forth from lordsport to the closest ferry but dont actually go on land. I got over 9 lords stuck so far and they cant seem to get away from there even when commanded (if marshal or cheat menu). Pls fix unplayable af. (Note I waited bout 100 days and nothing changed.)
