Crash when loading chunks

[Magnus Beck]

Plugin version: 7.2.24

Spigot username: NyhmsQuest

Issue: I'm trying to generate the world with worldborder but it just keeps crashing the server, I've tried with no custom biomes or structures and with the only plugins on the server being worldborder and ewg, I'm using minecraft version 1.11.2

Link to settings file (world-settings.json, possibly also biome settings if you have created your own): http://pastebin.com/ua7CwyFK

Try to reset the settings to EWG. The plugin fail to find out what biome it should generate.
