IG Map Visual of Terrain Hights

[Darker_Thought]

Hi there!

I got a problem with one of the maps I'm working on. When going into the module itself the "player's map" is not displaying the different Terrain Hights. In past maps the IG map has always displayed this but the current area(Even though its filled with contrasting Terrain differences) is "flat" when you look at it in the Player Map IG. Anyone know what the problem is?

Thanks before hand! ^^
