after save and load, that happened. cannot recover power via any buttons and methods. have never played this DLC properly since purchase. can i recover power from this?
Other than trying to play the run without saving and resuming, probably not. This old route I suspect is in the darkest bottom of the deepest dungeon at DTG HQ when it comes to making any further fixes.
You should always try to do something in one go since saving will cause problems on some routes. Other routes aren't as bad as this one.
