Currently the TDS boats are all messed up, the one in Thuliasaur is so bad it moves through the land mass. i dont even think you can use the boat to leave thule isle. I know when you come in on the boat you find yourself under water cause the boat is sunk down into the geometry. The TT boat to brothers isle is all choppy, it doesnt move correctly anymore it just warps along its path. I wonder if a Dev could take a look at this, i dont know when this started but its very lame considering those boats are the only way to those places
Nice to be proactive and all, but posting here for a dev to look at it seems like an exercise in frustration. Did you /bug report it in game? That's the best way to get it looked at.
