So, at the Power Plant I overcharged the switch, I heard the voice telling "Reactivating power" and the lights turned on so I didn't need anymore to use the torchlights... after that I entered unprepared the door to the first Boss and died...

Now when I return to the Power Plant it is dark, all the lights are off, but I can't turn them on again because the switch is already broken... I can open the doors that previously weren't accessible, so seems like the power is alredy active... but still no lights are on...

Is this a normal thing ?

I can't find informations about this as a possible bug.

Thanks
