So… playing through the episode, made the thaw elixir, then logged off for the evening. The elixir expired - I know that happens now, would have been good for it to be red flagged at the time, but hey. So I gathered ingredients again, bought a firestone from the shaman, and went back to the hot spring to re-make the elixir.
All I get is “I’m not ready. I’ll do this later.” Which sounds like I don’t have sufficient ingredients, but I definitely do.
Forum posts from 2016 seem to suggest I’d have to reset the episode entirely and play it through again - is that the really the case, and the intention of the game? If this is a bug I can’t think why it’s still present 5 years later.
Any help appreciated.
Sorted now. Thanks.
