I installed the mod but putting the files in GAMEDATA and the game is installed through steam. As for the "stock craft" I have no clue what your talking about. I didn't try rotating the missiles, but I'll try it on my next attempt. The thing is though is that I've tried EVERY missile, big to small, and not even the ones stated in the descriptions of the Patriot will snap to the Patriots silos, and same with the others.
This mod is awesome! my one gripe is that I can never get the missiles to sit properly on things like the TOW launcher or the Patriot. No matter how many different missiles I try, none of them with attach, and I've looked everywhere but cant find a solution. Any tips/help?
