Nevermind what I said earlier, cancelling the group's order freed it up.
EDIT:
Due to a fuck up on my part, there was a discovered Jump Gate in Sol which lead to Proxima Centauri, but there was a man-made small gate there. I sent the entire scanner fleet there to scrub that place until we knew everything about it and they were too big to go back through the gate, so they were basically stuck there. If they tried to fly back manually, they would eventually break down in the middle of nowhere and we would never find them again. So they waited until better Jump Gate technology was made, when it was finished I through together this rickety bucket of bolts that had 25 military-grade nuclear engines, 30 engineering spaces and it still had a 3000% annual failure rate, it only went at 251 km/s, too. It was a wonder that thing managed to hold together long enough to reach the Jump Gate in Sol which was 591 million miles away, even more shocking that it managed to survive the 20 days required to build the gate. By the time we got there and built the gate, pretty much the entire fleet of scanners except for the Mark II geological scanners, which were much less prone to failure, was gone. I hope I never need to use that Jump Gate ship again, it has such an insane failure rate that if I tried to send it across Sol it would probably fall apart.
Oh, and the AFR without the engineering spaces was around 80000%
