Ok, so I keep getting this whenever I run my map:
0 brushes (totalling 0 sides) discarded from clipping hulls
CreateBrush:
Error: Entity 0, Brush 3, Side 4: has a coplanar plane at (-912, 1728, 496), texture -3OUT_RK5
Error: brush with coplanar faces
Description: The map has a problem which must be fixed
Howto Fix: Check the file ZHLTProblems.html for a detailed explanation of this problem
