Hello !

I don't know if its because of the news mecanics : but when I'm trying to click the activate button to make the transformer go back to 100, it just... doesn't work ?

Its actually 66, and stays at 66 no matter the number of time I push the button. As anyone incountered  this issue ?

I already try quitting and restarting the game but it didn't change anything

Press the yellow button and get everything done in the panel, then press the red button and it should be working afterwards!

theres a button next to the reset button to open the maintenance panel where you need to adjust some knobs and dials to make the reset button work 

Thanks it worked ! I thouht we had to do this only when the transformers were down. So after checking, one of the puzzles indeed needed to be redone.
