Hello! I know this problem got brought up alot: Brush #: areaportal brush doesn't touch two areas. I know it means my area isn't sealed by func_areaportal completely. What I wanted to know is, is there a way to actually know where the leak is? I've narrowed down the leak to one room, but no matter what I do, no matter how sure I am to have sealed the room with areaportals, it's never good enough. I've hit a wall and don't know anymore how to fix this problem. I've tried loading a pointfile to no avail, and the brush numbers don't tell me anything new.
