Thanks for bringing up the point on the Must have at least := xxxx in the ConstructVehicle file - soon as I saw your post on it I reallized that has been the problem I've been pulling my hair out over in almost all of my AI's (why special designs haven't been being built in one, why one wasn't building enough carriers, and why I haven't been able to get the #@$&*% Krill and Orks to spend more than 55% - 60% of thier resources in maintenance). Thanks again - your post pointed out what I have been overlooking.

I'm at work so I can't check now, but try looking at how carriers are designed again. I'm sure that the Majority Ability is what is being used to determine that a carrier is to be used, and that whenever one of the specific hull types (Carrier, Transport, Colony) are used, the minimum requirements are filled automatically. I intend to check once I'm home, but try usind 4 carrier designs, one with Launch/Recover Fighters as the Must Have Ability, and the Majority spaces per one set at 10000, with no shields and only Supply as an Additional Ability with spaces per one set at 10; the second with Launch/Recover Fighters as the Must Have Ability, and the Majority spaces set at 0; with the third and fouth the same as the first two except having Cargo Storage as the Must Have Ability (have to have fighter bays available or the AI will just design a ship with the one cargo bay and fill the rest with supply) . I'm sure that all four will use carrier hulls, and that the two with Majority spaces set to 10000 will have one more fighter bay than the ones with Majority spaces set to 0; but I'm not sure if the Must have fighter bay will be counted towards the 50%, or will be in addition to it (I know for sure that it is in addition when dealling with weapons - but I there were some oddities with it when dealing with components with cargo storage abilities - like listing 3 Lay Mines Must Have Abilities with Cargo Storage as the Majority Ability and having the AI design a small transport with two mine layers and eight cargo bays), if it is in addition, then the two with Launch/Recover Fighters as a Must Have Ability will have one more fighter bay than the corresponding design with Cargo Storage.
