Anyone have any idea how Archaeology works? I have multiple quests that require fossils, but have no indication on how to acquire them. I've built an Archaeological Surveyor, which doesn't do anything but turn green and take up space. It says "You must take the quest found by digging before you can use this." What the heck does that mean? We've dug, we've got tunnels going. No one has any idea what to make of this. There's no information available anywhere about it. Is this even implemented?

Hey folks, maybe I missed something obvious, but can anyone point me in the right direction for a client-side download for 5.1? All I see is a link the the dedicated server files for 5.1, dedicated server files for 5.0, and client side files for 5.0?
