Defend Settlement conversation loop bug

[Kaorimoch]

Alrighty, I went to a settlement under attack and my defenses took care of the enemy easily. Since I had some armor and weapons on me, I went to a settler and since the defense was a success, the settler thanked me for helping them. And every time now that I talk to a settler to try and trade gear with them, I get the thank you speech over and over again.

Attempted solutions that failed.
Came back after a day.
Tried every settler.
Searched for a questid to use the completequest console command. No such quest exists.

Any ideas?

There is a repeating settlement defend quest regarding the Synths. It happened several times for me. You defend and settlers thank, but the quest isnt set as completed. Then it fails after a while when you leave. It sometimes helps to resurrect, through console command, a Synth and rekill it, but that doesn't always works. Besides this work around I haven't found or read a fix or other solution.

I ran into this loop as well. My only solution eventually was to purge the settlement.

The settlement defense mission not clearing is a different bug. For that, you need to target any dead enemies you find and "resurrect" in the console, and then kill them again, until you find the one that triggers the quest to end. This tends to happen a lot with the synth quests, when they execute the wayward synth as you're loading in and it doesn't register you being there, but the corpse is there.

Thanks for your help!

Without console:

-when you think you kill all the invaders, "completed" not showing even if you kill every one, wait something like 1hour in game (sit on a chair) the last remaining will show up and get kill by your 20 ppl at base and turret.

On PC, you can fix this with the console.
The bug is triggered when settlers are not correctly removed from the "WorkshopAttackDialogueFaction" faction by the appropriate script. This faction has the editor id 1125FE

Open the console, select the settler (so the settler's id appears on your screen), and type:
removefromfaction 1125FE

Turn_on_a_Dime, You are a genius! This has been driving me crazy. Such an easy fix. Thanks!

The remove faction fix worked for me. Thank you from the future!
