What ???

[Sigmar's Faithful]

eh, so the mission is stuck? That is a mission to kill all super mutants, and not rescue hostages, right?
Well try resurrect a super mutant and kill it again. Can't hurt.
If all else fails, use showquestobjectives 00157ca5 and use setstage to set the mission to the third to last stage.
Because in my experience there might be issues involving complete radiant quests using completequest command. If you set the stage to just before turning it in to the quest giver, it should resolve that issue.
Also save before you try that, at worst you will have to quit the game to desktop and start again, load the save, and try another stage.

There's 2 mutants down by the river by a winch, did you kill them they're easy to miss.

I have the same problem. I got the quest from Knight Rhys just after I had killed all the super mutants. A few mutants spawned, but there was no quest marker. I used the console to complete the quest and I think I broke it. Now Rhys is pissed at me every time he sees me. Can't get any more quests from him coz he thinks I'm still on the quest.
