The ore gen was coming from other mods, so I'm not too worried about that. only emery will disappear, so i'm not too worried. And I can always just replace some of the more vital missing blocks in creative.
There's any way to swap the old gas shales with the new ones? Updating might result in holes in the bedrock :S.
I've just released version 22.214.171.124. It fixes a few minor issues, but much more importantly it adds microcontrollers. These are new modules that can run lua programs from ComputerCraft and OpenComputers disks.
For more information please read this.
Weirdness: While testing out the husher on a creative world, using version 126.96.36.199, I had two strange things. First, even though I had a machine output facing into a Crystal Chest from Iron Chests, it was still spitting items into the world, and second, after shift-right clicking and removing the machine, then attempting to replace it against a Thermal Expansion Creative Portable Tank full of water, the world crashed with a fatal error, and would not load. No idea why.
