in the case the two missions I refer to are Look to the Rising Sun and The Far Side of the Sun. I added both, and upon map transfer to sector space, both vanished from my lists. Rising Sun appears as unadded/unplayed in the community authored list but i can't retake it. Far side of the Sun doesn't appear at all. And I know the mission hasn't been taken down as I'm talking with the Author in TS right now.
