I've been told by the AI scripters that it is best to leave that AI attribute out, as it often confuses the AI more than helping them. All the modern AI's don't use this attribute anyway and is coded differently.Hey, what do you think about also making a ZR@ RMS script so that you can include your terrains in the RMS, so that they may be used by your map script but the rest of the game is unaffected?
Edit: Also, it would be very nice if you could include the ai_info_map_type line (see the reference here) for each of the maps. It would allow AIs to play the maps better - even though some are of course very hard for them, it would help with the most. Just select the original map that you think resembles your map best for each (+ the michi or nomad flags).
