At some trader house boats, the trader loads outside of its house floating in mid air. It is also very annoying that when I am on such a traders boat, that I don't move the same as them, so when activating to trade, the window closes again, because a wave sent their boat moving up or down.

Another thing that happened various times was that when I died, I respawned back in the start-city, but my boat was still where I died. Maybe this is because the boat is tied to my floating home. Even when I die at Logansport, I still respawn in the starter town. Basically all I can do now is start a new game, as I will prolly die again while swimming to Logansport.
Luckily I created my own save/load game script, so I can just get back to the last save or one before.
