Todhb Yeah, basically exactly what I said was the issue. Both Hilstara and Varia have 0 HP in that save (I forgot that Altina is off doing her own thing at another pass in the next scene). I'll let SL know that this scenario came up then, I know we've seen these sorts of things before.
If you have an earlier save and want to continue playing blind, your best bet is to go to the pause before the Riala fight and make sure that both Hilstara and Varia get healed by Qum or Carina. Alternately, it could be the fight with Riala where Hilstara and Varia get knocked out, in which case repeat the fight to make sure that doesn't happen. Alternately, you could open the file you posted in a save editor and give them both whatever their maximum HP are. Or if you want to lean into the disaster run aspect, give them both 1 HP, although that effectively guarantees that you'll get a REALLY nasty outcome in the next sequence.
