Hi there @Whirlwind5089 this is a known issue, here's the bug report if you want to add your Me Too and add a reply if you'd like to do so. If you're on PC or Playstation you can share your save too if you want.
I've had this on and off for a while and in some locations it's helping to be there really early. It varies but lately it's been about 2am.
yes, i see this link to peeps also having this problem, but that was in june 2018 it was posted, i randomly have this problem now, july 2024
@Whirlwind5089As a test, you could try visiting Desert Bloom Park in Oasis Springs at about midnight. If I do that the rocks start spawning around 2am. If I'm any later I miss them until the next day, as I've mentioned on the bug report. But when I'm collecting then that's a workaround and I've just tested it in my game (on Xbox Series X with all packs). If I miss that time then nothing spawns except the occasional dirt patch but no rocks.
It is being investigated at least so hopefully it will be addressed in an upcoming patch.
Edit: if you have MWS and the dig piles in Tartosa for the Message Bottles are also not spawning, this one has been changeable for me but currently if I stay or live in that area they will eventually return. It's not like the dig piles where I just get there at midnight and wait. It's a frustrating one!
