ya so i was running a regular map scripting an insane comp into the ums version. ok but looking further into what made him so "insane" i see him creating a spawning pool with his first drone. even though in theory he has 50 minerals as i do. i tried removing minerals etc (should have made a trigger to kill his building if he hadn't gathered the resources in revenge LOL) but they just follow that same list of commands which allow them to ignore resource costs. the rest of the workers are still mining though.. lol
solution? this was done a year or 2 ago using the staredit scripts

ps: there are no other triggers besides the melee ones.

The insane difficulty just lets the computer cheat, if I remember correctly (though I could just be getting this mixed up with SC2). If you want them to play by the rules, use a non-insane script.

If you want your easier AIs to cheat on resources, just write a trigger giving them more resources.
