Hey everyone,
 
 I'm a newbie working on mapping with Quake 2 in Trenchbroom (loving the editor so far!)
 
 Unfortunately I can't seem to generate a map with proper lighting due to a leak while running QBSP3.
 
 I can still launch the map, however after compiling with QVIS3 it will be dark.
 
 In order to troubleshoot I started a new file which is a simple closed off room, ensured my "Snap to Grid" option is on, and that the room is indeed closed off.
 
 Here's what the compiler is doing:
