1. A simple re-entry to Dead Money after Dead Money is completed, I know there's some out there, but they're either bloated or broken (based on comment).. I had to use "Sierra Madre EXIT Door" mod as a last resort (it grants you trapdoor access right away just by starting quest). If you want do that, don't forget to grant player "Ghost Hunter" perk if player doesn't have one; maybe attach script to door to do that. 2. Better Boone "history points" to activate "I Forgot To Remember To Forget" quest, or alternative way to activate the quest if you miss out the history points. If you done all the parts that gives history points if you didn't bring Boone with you then missed out on the quest. By "Better history points" I mean, change it that it'll count even without Boone being with you, or alternative way if you couldn't make it work that way. If those aren't what you want to do then that's fine, not forcing you.
