can any one help me ? i can't activate the terminal cuz it's need power from the generator but i can't activate the generator . i get the prompt to do it but nothing happens . any idea in how to fix ? the fnvedit didn't show any conflict with any mod.

Hard to say, I'm not aware of any bugs with that part in general. So my first question would be, do you have what you need to fix the generator in the first place? I'd also suggest, if you have the science skill or the ID card to try and interact with PYTHON to have him fix it. That might get you around that problem.

yes i do have and the PYTHON is already fixed when i enter the room for the fist time

i already did the quest using the console using the activate code

The PYTHON was already fixed? That's odd, it should have been disabled in the one room there until activated. And you said that none of the mods you're running alters those assets?

Sounds like you ran into one odd little bug there then. Hope you don't run into anything else like that.

yeah ... now i have to find out if any other quest is bugged i already did almost all of main quests and some side ones
