[NCQE] Enigma of the Cove Rocks?

Same issue but I can't find a rock in ANY world. No mods or CC.

I went to the park in Oasis Springs and was able to complete the task. I was only getting dirt dig spots and frog logs. My sim actually lives in Foundry Cove. 

I'm having the same issue. No mods and no cc.

Bug Title:
No diggable rocks spawning in Foundry Cove (Willow Creek)

Platform:
PC

Bug Description:
When visiting the Foundry Cove neighborhood in Willow Creek, no diggable rocks (collectible dig sites) are spawning. I have visited this area three separate times, on different in-game days, and there are no rocks available to dig up.

I was looking for a special collectible stone, but even regular diggable rocks (that usually contain metals, crystals, or capsules) are not appearing in this neighborhood.

Steps to Reproduce:

Launch the game and load a save file.
Travel to Foundry Cove
Search the public space for diggable rocks.
No rocks are found to dig up.

Expected Behavior:
There should normally be multiple dig spots spawning in Foundry Cove, like in other neighborhoods. These are important for completing the Nature's calling quest. 

Actual Result:
No diggable rocks spawn, no matter how often I visit the area or what time of day it is in-game.

Do you use mods or custom content?
No

Additional Info:

Tested with and without mods.
Other Willow Creek neighborhoods (like Courtyard Lane) do spawn rocks correctly and wil complete the task. 
This issue has been happening for several in-game days.

That helps a great deal!  I've been searching for several days now for them.

You have to wait a little bit, I found it near the fishing sign.

Hi, for the second week of this challenge, you have to "dig for crystals stones" in Foundry Cove.

I've search EVERYWHERE and there is not even a single stone to dig ! I'm stuck because of this for two days now. Did someone have the same problem ? How to fix it ? Thank you.

I found one near the magical tree, and another by the potted plants garden in the area! They are amongst decorative rocks and were a little hard to spot at first. Hope this helps and good luck :)

Hi - I found this thread ISO an answer to this too. Cats and Dogs patch circa - 8 years ago. More importantly, out of sheer curiosity, I travelled to Oasis Springs, dug up a rock and that completed the task in my event pop-up. I hope this helps 

Try spending quite a bit of time in the neighbourhood and see if they will eventually appear. Depending on if you have dug them up lately, sometimes  it can take a while for the dig sites to respawn.
