Clay, yes its unlimited, that's always good, but when clay interferes with a good possible building plan and roads, it's a pain. Suggestion: -Make clay tile be able to harden by placing a campfire on top. ( this makes building plan and roads be put on top)... however, if you want to revert back to unhardened clay, you just have to use a pickaxe to break the hard surface. -Rising is no problem, but lowering is... Adding another option to "Scoop" lowers the clay and gives you 2X more clay/dirt/anything near the tile of the clay. and this lowers it ... however, scooping takes twice more time than digging and is only available when right clicking clay tile.
