Found in Version:
The Fast Travel boater at Seyda Neen (Sentius Veros) that is added by TR_Travels (Core, Preview, and Vvardenfell) is surrounded by 2 missing missing mesh exclamation points. It seems to be his face and torso that are missing. He can still be interacted with.
Mod Order (according to OpenMW):
The same occurs with the non-Preview version of the TR_Travels.esp
