All capitals need hangar points, or you get dev exe errors. Some of the current SoA 2 Elites dont have them, because they were moved from frigate slots. We didnt get around to doing this in 0.4e. So much to do so little time. This will be corrected in the 0.5 update.
A quick way to make a hangar point without a modeling program is to open the mesh file in wordpad. Copy the "Above" null (with all of its info under it). Paste it as a new entry. Rename it to "Hangar". Add 1 to the number of mesh nulls at the top. The strike craft will launch, and land "above" the ship, but it works for a temporary solution.
The ships entity. Mainly the Roletype, and StatCountType determine the ships role in the game. It is important that each faction have at least ONE of each specific StatCountType. Otherwise the AI has siezures, and will refuse to build anything at all, or it will be lethargic. The Roletype does not have to be the same as the StatCountType. Roletype determines how the ship itself behaves in game. You can have more than one roletype per ship (Entrenchment, and Diplomacy). For the AI to function properly it is the StatCountType that is important.
