How to get around a progress-breaking bug in 'Powered Up'?
Solution 1:
After a lot of attempts to finish the quest proper, I resorted to use a cheat code to break the deadlock.
SetStage Inst305 200
Will tell the game to move ahead to the "Quest complete" (200) stage of the Powered Up quest (Inst305). The problem with this solution is that one does not get to decide the whether the institute builds more Synths or better weapons. And there doesn't seem to be a way to indicate this decision via command codes (at least I was unable to find one). I'm not sure which one they are doing now, or if they are doing anything at all.
If anybody finds a way to do it without command codes, I'll accept that answer.
Solution 2:
There are two known bugs regarding this quest. According to the wiki there is an easy solution.
Sitting down will not start the meeting and you are unable to speak with the participants. One possible cause for this bug might be the destruction of the Brotherhood of Steel prior to finishing this quest.[verified]
- Leaving and re-entering the Institute may fix the problem.
When entering the reactor room Enrico Thompson will have exchanged his yellow institute coat for a blue one while still working in the Facilities department.[verified]
