We are introducing the first version of a Miner AI peasant (work in progress). If you place him near a mountain or other stony terrain, he will automatically mine stones for you. The selection of blocks was expanded with new diagonal variants and we added a few small changes here and there (new sounds, AI improvements, ragdoll).
