Have to admit, that i did not play any of the missions.
Opened all missions in a FRED2 Debug Build and fixed all errors it gave me and checked all other missions for similar errors. So i only fixed all errors technical wise, but not gameplay wise
So maybe the error in this mission is not the debriefing, but a cruiser with a wrong arrival cue
Well, fortunately this one only has 7 missions, so maybe i have time to squeeze it in for an extensive playtest to fix mission design errors... because the three other fixing/translation projects i am working on right now have 40+ missions each
