I'll tell you how. You don't have a SpecificStationCode declaration on YOUR wings of the plane where you try to load (manual or via loadout.ini file) an AA-12 missile. So practically, first, the "game" is looking if it is allowed to exist such weapon on your plane's wings. And all this is BECAUSE in the weapon files is specified that AA-12 goes ONLY for a wing where is specificated that AA-12 as..."SpecificStationCode". To make it work you have twoo way, the hard way and the easy way:
- the easy way, delete that line in the weapon's data
- the hard way, specify for EACH wing where you want to have an AA-12 that ONLY that missile goes there.
Actually there's a third way...lol, CREATE AA-12 specific stations the wings you want that weapon for your plane.
