Also, thralls will fall thru if they go up the stairs oat forward area of boat, and then get stuck in a port to top, drop loop until you leave and let the leash take affect and resets to normal position.
There is another boat just like the one mentioned above, on the east side of the new land masses, near New Khemi I think, it also has the same issues. Goes without saying, but should prolly be said regardless.
The new ships are pretty buggy. All the closed hatches will let you fall through them if you walk over them. The back ends of the ships look solid but you can swim through them. I saw something about this posted earlier, but can’t find the thread now, so putting it here again.
