Oh i tried hundreds of tweaks, and nothing gets the AI build properly. GTVA doesn't use Elysium class transports for resourcing no matter how hard i tell it that Elysium is a resourcer, and Shivans only build manticores and shaitans, and cruisers if it has lost all of its cruisers in the starting fleet.
I even luatraced the whole match, the AI properly calls for the functions when it wants to build ships, but it seemingly just can't find ships to build.
[edit]Ok, i tweaked around with classdefs, and now the AI builds. I also managed to get the GTVA use the Elysium class in resourcing operations. I can give anyone who wants a version of the mod where the AI knows how to build, just contact me via MSN, you can find my MSN adress in my profile.
