well the exact crash is:
G_Spawn() no free entities
this is bad. it never showed up with 9 v 9, but I guess at some point it would have. There is a maximum of 1024 entities allowed in the game at a single time. During normal gameplay, new entities are spawned (like grenades, airstrikes, gold crates, etc). Given that the default map has roughly 880 entities at initial spawn, I can see where the limit would be reached very easily (google search shows it has). Given that I needed to add 46 to provide the basic support for it, I think that this map is dead
I've yet to see it happen 9 v 9 and lower, so I guess use at your own risk...
