I recently found two blocks of this on surface level, but they didn't look like this. They looked like light when blocks, (I could only see one face of them before I drilled...I thought it was just light) and the hover blocks looked like light on three-four sides and ice on the others. When I collected them they were disks, saying refine minerals to build useful items. This was in creative mode. Anyone else experience this?
