Switch House upgrade not showing

[Jas2025]

I have made the Last home upgrade but the cave have not appeared. Robin worked on it for a few days but after nothing. I went back to her shop and now the options I'm given are the next upgrades. Not sure what to do?

Can you share a screenshot of your house and the upgrade menu at Robin’s?

Hi! Yes please the screenshots here. They are in French but basically my next option is for the community center.

The basement is there, you can walk down the steps in your kitchen. The basement is its own map, the steps are what changed on the house map.
