When units get repositioned, the carrier "Liscome Bay" is forgotten (!) "\Victory\Undeploy Troops" trigger is missing a reposition effect for the CVE Casablanca / "Liscome Bay" (campaign reward)
It's because a spawned units which you can't directly address like the rest. Question is if that was done intentionally, as there would be way to change it - but then there are also two airfields on those islands, so maybe it was just thought to be unneeded.
Maybe it was not possible to do at the time the campaign came out or it was forgotten.
It's not a real biggie as there are air exit hexes all around (but NO airfields on the western islands where the second part of the mission transports all my units to), but it would be convenient to have the carrier there, it could save a turn or so for my tac. bombers.
