Lost Shipwreck glitches outside interiour when Water walking is active and entering the lower decks. (v0.47RC3)
During a modded play through (and later unmodded to verify that this is an issue) I stumbled on this wreck: https://en.uesp.net/wiki/Morrowind:Lost_Shipwreck
I had water walking active, went to the hatch and entered a ship.
What I instead got was this weird nothingness and the interior of a ship.
To reproduce this; give yourself superpowers, jump to this ship linked above, in the console execute player->setwaterwalking 1
and enter the hatch to the lower decks. Enjoy the glitched view of the interior.
