So that's probably the issue? Damn.
Glad to know it's not a problem with the mod, then. I'll have to search Fallout Wikia for something to let me bypass this. I put several hours of Iron Man into getting the MQ done for this base, and I shalt not leave it uninhabited.
I'm stunned that you were able to get through the MQ as level 7? Holy [censored]? hehe.
There is a combat challenge to get that base that, as a level 7, you would have to do a -killall- in the console to win.
I bet that my quest character would offer you the quest if you walked into the place, though. That particular trigger doesn't care what level you are, if I recall. Let me see what I can figure out as a good way to get you to the area.
