I'm losing my mind over this leak. Selecting the whole map shows no entities with origins where the point file shows, there are no brushes or anything where the point file shows, and I've even tried just boxing off the level that it is closest to, to no avail.
To get the leak, compile spawn, course 4 and any other course.
Strangely, it only produces a leak if course 4 is compiled with another course. I was able to compile spawn and course 4 by itself with no leaks.
