I'm currently doing the quest for the boomers were you have to activate the generators and the breaker. I have activated the Sonic Emitter, activated the generators and the breaker box, killed the ants, etc but the objective still says to activate the generators. I would reload a save, but the last one is a corrupt save far behind were i am now. Could somebody help with this?

Perhaps you just dropped the Sonic Emitter? After dropping it, you must then access and activate it. Hope this helps.
