Not allowed to defend my outpost from Synths (spoilers?)

[Yuni]

My outpost is under attack. I went to defend it. I'm allied with the institute. Synths are ransacking it. I let my settlers defend themselves, but it won't complete the quest, and if I leave, it fails the quest and my outpost is almost burned to the ground.

 

I can't shoot the synths or it will piss off my faction, and if my turrets do the job for me, the quest doesn't complete.

 

Ideas anyone?

If you have no mods installed, then I'd call it a bug and it needs to be reported (somehow?) to Bethesda and send them the save game file if needed.

I did some more reading up on it and more experimenting. After like a dozen tries it somehow didn't fail to defend the base, but it even says on the wiki that this... uhm.

It says on the wiki that even after you become the director of the institute, they still attack your settlements with synths. I think Bethesda might be aware.

As for failing it, happens to me at the alley settlement a lot. What's happened is one of the attackers has spawned inside somewhere they can't get out of, i.e. can't reach the settlement to attack it and/or be killed. I watched how the turrets and settlers were aiming, and could hear them doing combat taunts, found them inside one of the buildings. I used the console to bring them out and settlers killed em off quick. I got a similar situation at another settlement.. Tenpines Bluff? where the attacker was half inside a rock formation and stuck where nobody had a line of sight on them. They were probably 100% inside the rock and just clipping out as they tried to move. So.. if you don't get the success message for defending a settlement, open the console, tfc, and start checking around for stuck attackers.
