A new version of Big Dig has been pushed to address an incompatibility between Galacticraft and Easy Crafting. Easy Crafting has been removed and replaced with the mod Project Bench, which provides similar functionality to Red Power 2's project bench, and which is fully compatible with other mods in Big Dig. Additionally, Treecapitator support has been added for Natura's trees.
The new version is already marked as recommended and users will be prompted to download it the next time they launch Big Dig. The new server version is available here.
