I'm on the mission where you have to use a captured Mara to scan the big Shivan destroyer and the Cain while remaining undetected... I have no problems with all the scanning, but afterwards I get told to get a safe distance away and not warp out until they tell me to.
However, no matter how far away I go, they don't tell me. I even tried setting the time accel to x64, going to eat lunch, and returning an hour later... no luck.
Also, I tried to get past this with CSGedit, but apparently that can't load .cs2 files, which is what campaign progress appears to be currently saved as.
