This is due to oversized water mesh extents in the WoW data files. + - **Current Workaround**: Water heights are lowered by 1 unit in Stormwind (tiles 28-50, 28-52) for surfaces above 94 units, with a 20-unit exclusion zone around the moonwell (-8755.9, 1108.9, 96.1). This hides most problem water while keeping canals and the moonwell functional. + - **Limitation**: Some park water may still be visible. The workaround uses hardcoded coordinates and height thresholds rather than fixing the root cause. + - **Proper Fix**: Would require trimming water surface meshes to actual boundaries in ADT/WMO data, or implementing spatial clipping at render time.
