a big wtf for me. My map suddenly developed a leak, and I followed the portal line, it seems to be going through my wooden wall (here) then once through the wall, into a big pillar of nodraw (here) None of these or surrounding brushes are entitys and Ive been replacing the brushes and nothing seems to work. Any ideas? (Also, unrelated, but my overlays stop being applied to faces after awhile, why is that?) Thanks!
