I make a few maps every now and then, recently adapting 8-player maps for 2-player ensuring they start next to each other. This requires "use map settings" and triggers to set the 6 computer opponents working.
On most maps, it all works fine.
On some maps, the Zerg build an extra Hatchery and occasionally a Spawning Pool, but nothing more.
How can this be avoided?
I'm simply using the "Expansion Custom Level" AI script, so that they use Brood War units and treat the map as if it's melee.
Many thanks.
