finite cave
Started a new game after release (NG+). And it turns out that in the mines there aren't any mystery rocks. Old files started before 1.2 have them still.
Checked before making an offering to the goddess and after.
Reproduction Steps - start a new game, go to the mines and find no mystery rocks.
Repro Rate - have myself tested only in one game, but other players in #🐔coral-general have also stated that they had this issue
Game Platform - Steam
Game Version v1.2-1238
Save and backups attached

Saves done before 1.2 but have not progressed til spring 5 also have no mystery rocks

Haven't seen this issue on Xbox Series X, but that's on a new MP game, not a NG+ (didnt know there was one tbh, so may not be a thing on Console, or I've just missed it!)

attached is an old save with mystery rocks, and videos from both saves
Edit: Through further playing mystery rocks appeared right after making a second offering at the altar. That wasn't the case previously with 1.1b where they were there at the start and offerings were affecting their amount.
Can you clarify if this is new intended design?
Edit2: Loot from mystery rocks is now registering in the journal. Wasn't like this before. Also clarifying if this is new and intended?
shrewd hare
received report that someone who did a ng+ still have said rocks
it does not seem to be tied to mining skill or time or event one thing I haven't tested out is if town ranks affect the spawn
shrewd hare
this is the mystery rock in question

This seems to be tied to goddess offerings, after giving 2 offerings it started appearing in low quantities

Hi everyone @finite cave @rancid surge @shrewd hare , thank you for reaching out to us! Yes, we can confirm that this is the current intended design. The mystery rocks start showing up after you complete the 2nd offering at the Lake Temple. At first, you’ll see just a few, but more will appear gradually as you keep progressing through the offerings 
We hope this helps clear things up! If you have any other questions or run into any issues along the way, please don’t hesitate to reach out. We're always happy to help!

Thanks. Can I clarify also about mystery rocks, is their loot supposed to register in the journal as “caught” or not?
It wasn’t previously in 1.1b
