I was out hunting in the game and came upon a greyling. It ignored me and started to attack an old fence next to one of those boar pen structures. It's very far from any of our structures and I really don't want mobs attacking abandoned structures!

Reclaiming and restoring abandoned structures is something we enjoy, and we'd love to find many more neat things as we explore the world. I don't think this was intended behaviour because exploration is a major aspect of the gameplay and the devs make it clear that they want players to enjoy that activity, so I hope it will be fixed ASAP. I don't want to find abandoned villages in absolute ruin and with nothing to bother claiming.

Additionally, as many other players have pointed out, the new AI needs tweaking so that enemies don't ignore players and go to bang on a wall instead. I thought this was only meant to happen when the enemies can't get to the player. Now the AI just wants to destroy any structure, whether it belongs to the player or not, and regardless of a player standing right beside them.
