Ahh, I think it might be a bug that happened in between game fixes. Can you go to Shrine > Special Game Code and type "Poket" and see if that fixes it?
Viewing post in Question for future development.
Ahhhh, the hot spring upgrade for the shrine isn't actually available yet for this version, my apologies! (I was thinking about the most recent build for the patreon for this one). If you have Velani accessible via the devout list, then you should be good to go, and the hot spring upgrade will happen automatically once the build with it is live!
