Cant rescue hostages from abandoned outpost

Hey sailors, I've had this problem where I failed taking over an abandoned outpost despite doing EVERYTHING. Stuff like killing off all the bandits, uncuffing the hostages, and for some reason i even restored the power thinking that would do the trick (it didn't). I gave up and lost 3k credits but id rather have left than waste another hour figuring out what i was doing wrong. Has anyone had the same problem?
