I think the Aether dimension is messed up on the RPG server. Typically it is supposed to spawn Zephyrs which are flying creatures that blow you around but i'm seeing instead 'Pet Spider Lv.0' which do the Zephyr attack of blowing you around. I wonder if the issues with the Aether are fully or in part due to incorrect monsters spawning. Would resetting the Aether dimension fix that problem?
