I'm trying to use presets to make a superflat map in 1.7.10, and it doesn't seem to want to use item names as it just resets the preset the second i exit that menu. It does, however, seem to be willing to take the old number ids. So how would i go about using a block that has metadata(?) such as instead of dirt 3, i want to use podzol 3:2 or acacia wood planks 5:4?
