The campaign AI works pretty nicely, the biggest issues I've run into so far is the AI suiciding to the PD on "Golden Crystal". It happens everytime I tried to play the map, so I think it should be fairly easy to reproduce.
The AI would send their com to the bottom left of top left, tank PD fire then eventully retreat. Then after will they would go back this will repeat. The com normally dying trying to overcharge the PD.
