I was wondering, in the past I have been able to get Eric the ghoul his extra power and optimize the broken hills power grid for extra xp at the same time, but in my last game I cant do it. I was wondering what exactly you need to do to trigger the extra xp while fiddling with the controls - science level, quest order, do you need to talk to someone about a power problem, I've talked to brian alot and no joy.Help me vault dwellers!
