What exactly are you supposed to do with regards to missions needing to be completed prior to advancement in a campaign? The FRED help docs are lackluster to say the least with regards to the Campaign Editor. I've got some super-old missions for some long-dead campaign that I want to dump into a VP file and release so my efforts weren't a complete waste of time but the campaign thing is annoying. Even if I don't complete a mission, it allows me to advance to the next mission. I don't get it. One mission it was even playing the "sad" debrief music, it let me advance . . . what's the deal?
Any help would be most appreciated.
