Looking over the code, looks like Slark's Pounce, Ursa's Overpower and Visage's Summon Familiars will need to be rewritten, as they will cause conflicts with the AI script and result in WC3 crashing.
If you find a crash unrelated to any of these three heroes, let me know. I'm working on a fix for the aforementioned abilities.
-dm is still known to be unstable on the AI map. Until I figure out why it will continue to be so.
