Look in your "Terrain / Data /" folder for the sub-folders under there, and convert any ZHF files into RAW format, and then look in the upper left corner for the "pillar", and down along the left edge for a "wave" looking anomaly of about six pixels wide of different colored pixels. Your existing pixel pillar isn't "brown" down near the water? I wonder if the "White" is lack of color, because the definition of the pixels is "out of bounds"... hmmm...
I wonder if some "binary manipulation" (aka: hex editing) of the files would work...
