Bur for crafting gravitool craft --> electric wrench(gregtech) but the craft is in need of the industrial craft I sorry for my bad English
If you want to craft the gravitool, just ask a moderator to give you an IC2 electric wrench in exchange for a gregtech one. Unfortunately it isn't so much of a bug as just a crafting incompatibility with gregtech and Gravisuite; As gregtech overrides the default IC2 wrench with his own. I will see what I can do to make a recipe that includes the gregtech wrench and not the IC2 one, but it might take a little while since I don't exactly have the resources to do it right now.
