Sorry to revamp an old thread. I spent an hour searching the forum about the exactly above problem and didnīt find any clue or fix.
I have a new installation with more or less the sobers mods list. All then last version. But sometimes when I surface, the crew donīt moves to the deck. Even in calm wheater - clear, nofog, 5m/s. Using last TDW UI.
The unique solution until now is to save/reload the game.
This is really odd and annoy my game play.
Any idea?
