Colonist's won't clean up rock?

[Riker13]

I had just made a big room in a mountain, and I made carpets in it but the rock in it makes it look horrible.... Is this a bug? Or is there a solution?

Make sure it's a home zone and your colonists aren't busy with something else.

Oh, I totally was focused on my food situation and didn't realize to add a home zone..... Thanks!

I did manual priorities on all of them and there are cleaning every single thing in that home zone XD
