A few years ago, I had connected the river at Tarendrelle to the one at Remen, so Seanchan could make a quick hop to use the Lugard Market Hall. That connection was also used as a get out of jail free card, and thus was removed.
I have put in a one-way riverboat captain with a no-quit check, so you can still go to LMH. Also, the boat takes mounts, whereas the previous canoe/ raft option didn't. Say fare, passage, embark or ship to board.
I put a door on the ship in case someone gets stuck. Just interact with the door, in case this happens.
