The first one after jumping from the bathroom down into the new area to chase the scrang, the moment i hit it whether i run or not, whatever buttons i press, or whether autodash is on or off, i die.
I've played the game, and reach that point you die, and I didn't die at the very first purifier or any other only if I don't stay for more than a second. Perhaps this save file could help you. This is all I can do.
