Teleporting in Ultimate Galleon and The Battlespire spawns the player character underneath the ship

On Ultimate Galleon, sometimes when you use the ship's fast travel or get out of the interior of the ship, you spawn in water underneath the ship and not correctly on its deck (this ofc doesn't happen in Morrowind.exe, where you always spawn correctly on the ship).

Here's a video demonstration and the OpenMW log: 2023-07-27_17-01-22.mkvopenmw.log

Tested on OpenMW 0.49, Windows 11.

Likely the same problem happens also with this other mod: The Battlespire. The first time Tadas teleports you with the Solar Ship from Tel Fyr to the Battlespire, sometimes you spawn underneath the ship (on Sadrith Mora), sometimes you spawn correctly (on the ship). But in most of my attempts, you spawn underneath the ship.
