seems like i managed to get this bug:
"After retrieving all the components for the air filtration system and returning them to the Brotherhood, it is possible to tell McNamara that the air filtration system problem is fixed, and he will have a change of judgment about his ways and end the lockdown, ending the quest and giving you EXP. However, after this, even though the quest is completed, you can still go to Hardin and tell him that McNamara broke the Chain That Binds, and you will receive the EXP for completing the quest this way, too. This glitches the game so that Hardin will never oust McNamara and you can never have any actual dialogue with them beyond this point, except from them stating they are preparing for one another. "

is there any way to fix this? havnt found any solutions for it, and going back to a older save is out of the question. anyway of sorting this bug with the geck or console command?
