Noggit - Error

Ok This is what I have done sucessfully.
*Created a map that is accessable in-game.
*Modified AreaTable.dbc
*Modified Map.dbc
Problem: I can enter the map succesfully and it doesnt say unknown in /who. But there is a really annoying graphical glitch.
The graphic glitch only shows when looking towards the water. Does not happen on other maps like retail ones. Only on this map.
Please help. I have no idea how it got screwed like this as It wasnt bugged until I modified AreaTable.dbc.
NOTE: I do not own the rights to the game and all that goes with it, I will remove this immediatly upon request. This is merely for studying promotion, As I'm very interested in how blizzard is handling the creation of this game.
