The computer keeps trying to move the dropship to assist with its troops, but the dropships only purpose is to sit above a beacon to indicate which unit the player is choosing by stepping on the beacon. I currently have a Move trigger keeping him there, but it still moves a few yards before being moved back to the location it should stay at. Is there a way to just annihilate all default AI? If so, I'll have to reinstate some of the AI im sure, as this computer player has turrets and traps that need to be constantly killing enemies to prevent the map from maxing. HALP

it seems like you don't have hyper triggers in your map, which should be added for any map in my opinion, hyper triggers make so the triggers fire about 12 times per second compared to the normal once every 2 seconds. Theirs that or you can maybe give that dropship to player 9-11 after it appears there.
here is a link to what hyper triggers are if you don't know http://www.staredit.net/wiki.php?article=Hyper_Triggers

Actually I do, I have hypers on the enemy computer so that I can control the spawns more accurately and efficiently. However, the rpg is based on mud combos, so I can't add any more triggers to other players. I never thought of player 9, though, that should actually help me with multiple problems, so I will give that a shot it should work thanks.

You can always add triggers to other players. Neutral units have a very basic AI (the same as humans). Player 12 has no AI, so it will never issue an order or attack.

Why don't you set it to a nuetral player (player 12) that way it doesn't keep moving and if sitting there is it's only purpose, then it doesn't harm anything.
