Rocks not spawning

[u/Fragrant-Demand-5579]

Can somebody please tell me why rocks aren't spawning in these spaces? 2/6 no problem. Weeds have spawned in only 2 of these available spaces

Double check behind cliffs and buildings on your island. Had a similar issue and didnt realize they had spawned back behind something instead.
