Hey !
Look like there is no gold ore gen.
Tried to redownload several time, plus modify config, but gold ore don't spawn.

After using this :
"block": "minecrat:gold_ore",
"size": 80,
"count": 90,
"bottomOffset": 0,
"topOffset": 0,
"maxY": 50
I saw that the world generate the "space" for gold ore,
But it's void.

You missed an f in Minecraft

that's actually due to the missing f

yeah... not sure what's causing this-- I noticed it with refined machinery ore, trying to figure it out now.

Fixed in 1.4.0.
