I'm using World Painter to create a custom map, and I keep getting a BiomeDecorator error http://pastebin.com/2S8KRLnC. All I do is go in-game, explore the map, and after like 30 seconds, I get this error and the server becomes unresponsive, eventually shutting down. I used Multiverse to import then TP to the map. If you need any special information about the custom world, ask! Thanks. My World Painter world used "Void" as the border, which seemed to have been causing the problem. I set the border to "Water" instead, which worked. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
