Also just because the current engine can't be repaired, doesn't mean they can't just make her a new one, pull out the old one, and revivify her once it's replaced. I would only be worried if they added some dialogue from Barcus or Dammon saying explicitly "we can't fix your engine because xyz".
Also previously when they "polished dialogue" they didn't actually change anything said unless explicitly stated in the notes. In the past it meant sound quality, animation clipping, etc.
