Talking to Ingram after doing this, however, still triggers the Mass Fusion dialogue. I used different combinations of the commands 'resetquest InstMassFusion' and 'setstage InstMassFusion 5' - the first stage - to try to roll back the quest. Speaking to Ingram at this point, however, triggers the Mass Fusion dialogue. The problem is, Outside the Wire (and possibly other Brotherhood quests) requires me to speak to Ingram. Choosing the Brotherhood means speaking with Proctor Ingram. I wish to belay this decision until I have completed more quests for either faction. Mass Fusion forces you to choose between the Institute and the Brotherhood. After trying several combinations of console commands, I can't seem to get it to work right. I'm trying to either reset the quest Mass Fusion or progress beyond the quest Outside the Wire. I only have a quicksave for the scenario I'm about to describe. Let me start off by saying that, no, I don't have an old enough save file that I can use to start the quest over.
