Why is there no autonomous activator or alternatives, like the ExtraUtils2 Mechanical User, or even an Auto Sieve that I can find, in FTB Sky adventures? Am I missing something or am I really meant to manually sieve gravel until I've built the Void Ore Miner? I don't see any mention of this in the quest book either. I'm hoping not to have to use bees or chickens right away as I don't have much experience with them and don't know how to start with them on a skyblock, but it seems like that's what the pack's pointing towards. Advice?
