I tried to create a new Tier for the ''CrateKeys'' plugin, but my whole config resets when I reloaded my server. It's very weird but I dont know what I did wrog. Can someone take a look at my config and can maybe fix it?

Old Config with 1 tier (Vote): http://pastebin.com/yX8Nwvuw

New Config with second ier (Rare): http://pastebin.com/yXGt2zGP

Thanks alot!
