I am making a version of flatgrass from scratch....
Same X & Y size as flatgrass, Z size is about 1024 shorter.
16 info_player_start's dead center on the ground piece
1 light_environment dead center of it all in the air
2 fence-textured brushes in one corner to designate a "deathmatch" area
Several brushes in opposite corner (prop_dynamic) as a jail (for NewAdmin Purposes)
5 "skybox" brushes making up the cube for the outer edges of the map.
I start compiling with all settings on normal (bsp, vis, rad)
It gets stuck on "Portal Flow"...
1....2....3....4....5.. <---- that's how far it gets and then it freezes.
