Sorry for the late announcement and RPG downtime. It is currently being transferred because the node it has been running on is overloaded (which largely attributes to the lag).
Update 1.2.2_4 adds a revised IP for the new server node. In addition, we are doing a test to see if the current overworld is contributing to the lag, so we have set it aside and a new world has been temporarily generated. Please help us test this and play on it for a few days so we can analyze the lag on a clean, temporary slate.
