The current objective is to follow defender sibley into the simulation room. The objective can't be completed because sibley is still in the outside area and can't seem to figure out how to get inside - he just stands on the elevator and looks silly. I've tried waiting for a day inside the outcast base, travelling away and then back, but no dice - he's still outside when I check. Attaching the save file if anyone wants to take a look.

Slower leveling is a mod I made myself as a workaround to the slow loading issue with TTW_optionals - all it does is double iXP_bump from 150 to 300.
(P.S. sorry, I think I left Enclave Radio enabled - I like the marches)
Edit - added load order - useful to know if someone is going to try loading the save. It should load up on a bland game with nothing but TTW_fixes, though the character's XP and level may come out funny.
Second edit - if anyone else bumps into this in the meantime, you can get past the broken stage with a couple of console commands:
setstage 0B0009BE 45
player.additem 0B00A6C0 1
The first command advances the objective from 40 (follow sibley) to 45 (put on the suit), but unfortunately the NPCs won't give you a suit when you do this, so you have to use the second command to give yourself one. When you equip it the quest should continue normally.
