Hmm, how come this stuff never happens when I'm playing it?
It appears to have crashed when it built a hive and just never recovered. I've been hoping it doesn't happen much, but it occasionaly does this crap once in a while kinda like how blizzard's AI breaks on BGH, lol.
One thing I've always had trouble with this AI is that it in rare cases softlocks when it tries to go hive. All zerg scripts besides Myk ones do this, and I never really learned how to handle it. The zerg script is actually a lot less complex than the terran and protoss ones, but is the most prone to severely failing.
Upon a second look, I think it's because the hive buildings have a higher priority and it's screwing it up.
If it happens again, and I can try to tweak it a little. Overall, I feel that messing with priorities does more damage than it helps.
