The Off_Solid block works fine, it's solid when off, and not solid when on. The On_Solid, however, doesn't work no matter what I've tried. I have it set in the right Hex value spot (201). The description of the block on this site says it's supposed to act like tile 1030. I set the block to act like tile 1030, it just acts like tile 130; 1030 isn't even a valid tile, right?
