After installing update 18.2, you might see a "No room on the map" error when tapping on resource spheres (glass spheres with objects inside) in the Dream Garden.
Our team is aware of this issue and is already working on a fix.
Good news: You can safely ignore the error message for now. Just tap the glass spheres again — the objects will still be placed on the map as expected.
Thanks for your patience and understanding while we work on resolving this!
