This bizarre bug gave me another super mutant “cure”, it is very easy you just gotta access the barter menu and offer any trash you’re currently carrying (the “cure” is worth 0.00 bucks).
The pack leader might have teleported you to the cave after you greeted him, if you’re a evil character. If you use the terminal to open the vault door and try to get to the elevator again, the Deathclaw will start a conversation with you automatically.
Before you go ahead and take lots of Jet canisters, I urge you to create a new save (F5 key)! I haven’t tested this exploit with RPU!
You open the backpack, hover the cursor to the Jet icon, drag it to item slot 1 or slot 2, and target the Chosen One when prompted. Take another one. Save game. If you tried to immediately gain more AP through Jet you would lose a Jet canister and receive no buffs. But if you quit your current game, select the recently created save and take another Jet, it should work. After spending some time following this strat, you can call & use the vault 13 elevator uninterrupted, like in the video.
