1.3 PATCH PLAN
The server is staying in 1.2.5 until all the plugins we require to work on are updated.
1. Wait for Bukkit to update.
2. Check if Factions is updated.
3. Check if RoyalCommands is updated.
4. Check if Vault, Spout, etc. are updated.
5. Update to 1.3.
6. Relaunch Dunmel for 1.3.
A WAY TO GET ON DURING THIS PERIOD
Using the Minecraft tool MCNostalgia, which allows you to downgrade your Minecraft .jar. This is useful not only for getting on downgraded servers, but also using mods that haven’t updated. I actually used this to play the 1.7.3 version of Aether, before it updated to 1.2.5.
So, using this, you can get on my server with no error.
