I see, my mistake. Thanks for clarifying.

@Vanguard That isn't a bug. The soil types still have their original names, so if you collect red sand as clay, it will be called "red sand" since that's the name of the soil and the "red sand" will be usable as clay.

Ran into a bug with this mod. I'm using this mod and not your sand anywhere nor clay/sand anywhere mods. I set up a zone for clay collection over red sand and created a work order for clay collection. I watched a Dwarf with the clay collection job go to that area and collect red sand instead. I confirmed that the work order showed that one of the clay collections had been completed.

Love ceramic

I don't like sand; it's coarse, and rough, and irritating, and it gets everywhere. Not like here; here, everything is soft and smooth malleable.
