First off, let me start with this. I am quite mod friendly, and have quite a lengthy list installed, and would be happy to list every single one if necessary. Also, I am extremely new to posting, so feel free to give tips on how to improve this :)

It seems no matter what I do, or how I go about it, the mission to retrieve the beryllium agitator is BROKEN. As in, it never TRULY ends.. This is (annoyingly) in both the Institue's quest line, AND the BoS. The missions Mass Fusion, and Spoils of War respectively.

For clarification, the leadup works entirely fine. I talk to the quest giver, convince them to buzz off and let me go alone(I only bring dogmeat ANYWHERE, fight me.) And I get there perfectly fine. I can retrieve the agitator with absolutely no trouble as well. I return, either stick it in the Institue's reactor, OR push it into Liberty Prime's slot(lol) and the rest of the mission goes off without a hitch. Every time. Then, the quest ends. However, LATER, for a seemingly random reason, and a seemingly random amount of time has passed, the quest, ONLY EVER from the faction I sided with, (I don't ever get Mass Fusion when I do the BoS mission, and vice versa) it just.. starts again. The prompt to talk to.. Allie fillmore, I believe, OR Proctor Ingram, appears. Like I just started. It's annoying and VERY repetitive. It DOES NOT go away. If I stop the mission via an external source, such as the quest manipulation mod, it will start again later with no prompt.

I have done at least 3 playthroughs with this issue, and I can ignore it. But if there's at least a reason why, I would love to know it. It's been driving me mad, I have to admit.
