The Federation quest to "Win any War Zone", which tells you to go to Kerrat in the Donatu sector, is not completable. Everyone in the zone channel had the same problem. Winning does not complete the quest.
Same bug for me. Read the nodes, killed the hubs, beat the enemies, waited to time out and did all that again, warped out, went back in, did it all again to make sure. No reward, and quest is still in my journal.
