Hey Rongel, I just got done changing this for Zedi's Campaign files, and I got a hunch that maybe the lifeboats had the same thing going on. The .cfg files in the Sea folder is pointing to a .tga for the texture, but the texture you have included in the mod is a .dds. Now, everything still works in game with this setup, but I wonder if we shouldn't go ahead and change it to .dds.
Like I said, I made this change in Zedi's campaign files, and I did not see a difference. But, I would think things might run smoother if we were in fact pointing to the correct texture file.
Just thought I would give you a heads up on this comrade.
