A small amount of background -- Team 1 is humans only, 0 reinforcements, completing objectives.

Now the questions:
I haven't gotten to the point of needing to do this yet, but:
1-If I have multiple classes with a max of 1 unit each, but no reinforcements, will additional players be able to select a class even if there are no reinforcements?
2-I've never had good luck forcing AI not to be on team 1. They always seem to take any slots I have. If there's no reinforcements, they won't spawn, right? (I suppose I could just not get team 1 an AI goal)

2. Dunno if this is what you need...but I always use this to stop AI spawning:

AllowAISpawn(ATT, false)

Hmm, that works nicely. Thanks!
