Friends can't use Super Carrier!

[FlintMcgee]

So I've made a mission for me and my friend and have hosted it on my computer. I've put down 2 carriers: CVN-74 and CVN-73. I spawned on the CVN-74 (non-supercarrier) perfectly, but my friend couldn't spawn on his carrier, the CVN-73 (supercarrier). He would always spawn in the air. Now I think that just because I don't have the super carrier, my friends can't use it as well, which I find kind of dumb because I have tested this theory. I sent my friend who has the super carrier the mission file, and when he ran it, he could spawn and I could spawn on carriers, but when I ran it, it spawned me on the carrier and him in the air.
