Trevelly, I had the same problem as Poacher, except this was trying to get into Wilhelm....I could just about pinpoint everytime when the game was going to crash. As you come from the north you can either pass-by the very small island (Mellum) entering the Jade region of the waters, on the port or starboard side it did'nt matter.

Just where the word Jade is, thats the boundary line to the CTD...
Hope this helps some with bug stamping.
