I recently updated to the mindcrack pack v8 (the unstable-ish one) and got started on tier 3 of thaumcraft. After discovering a couple of cool looking new things I noticed that an obsidian pillar has been added to the world-gen. I have been pretty liberal about exploring my world as I was under the impression that world-gen had been completed. Mind you I don't really mind new things being added as far as items and machines but world-gen things can get kind of difficult to come across after making ones world so huge. Really my question is will this be happening a lot and just I wanted to get other opinion on the matter.
