I remember that a long time ago, extrabees had support for Gregtech. When you update to 1.12, I would like you to support TechReborn as it's a remake of Gregtech 2.

You can find more informations playing FTB Ultimate but if you want I can make a spreasheet with mutations and centrifuge recipes.

I have added back the sodalite, pyrite, bauxite, cinnabar and sphalerite bees.

Thank you!
