Oh I was pretty sure too, just wondering if we ever actually caught him 'in the act'. :) I do recall him harvesting the forest on my hill and when I asked him to replant he planted acacia trees 0.0 so I'm not too upset he's gone, anyway lol.
I've managed to find most biomes out there, including the Mesa biome I was searching so hard for. I like to have a source of hardened clay for building, it is my favorite material. Though I am currently looking for a mega taiga region. I managed to get my horse stuck in a ravine and am currently digging him out, oye.
