Cloud Forming After Removing Slabs

Summary:
I placed a standing wall as if for a defense wall around my town. Wanting it to look more of a castle
I placed Slabs on top of the Free Standing Wall. After removing the Free Standing Wall the Slabs were hovering. I then removed the Slabs in Pause Mode. After all Slabs were removed the cloud appeared. See pictures for what the bug looks like
