I'm trying to create save file that I can return to and complete any of the faction endings. I'm approaching the Molecular Level, and I'm wondering if I may need to make that the crux point for the save, or if I can safely continue further into the game with all the options open.
1. Does Inside Job require building the device at Sanctuary Hills?
2. Are there any workarounds for the issue where Sturges becomes a non-settler, or is it permanent?
3. I've read one wiki entry that says "Defend the Castle" requires that both "Banished From The Institute" and "Inside Job" must be completed for it to activate. Is this correct, and does that mean that the minuteman questline can become locked out if you build the transporter for a different faction?
4. Are there any major faction quests that get locked out by decisions made during Molecular Level?
Thanks in advance for any answers.
