I don't think that was the case. I told my teammates of my problem, and they all thought that it was weird. They asked me a whole bunch of questions like I was a noob like if I had enough pylons and whatnot. They were all zerg, so they were mass producing weapons of mass destruction without any sign of problems.

Possibly, but I was the game creator, and I've used this map multiple times without any such problems. I normally play Zerg, and this time I was playing Protoss, but I don't see why there would be any restrictions on what 'toss could build.
