[v1.10.0] Null Pointer Exception

[gunnibunny]

The update fixed the problems my players where having when changing between Worldgroups and loosing inventories. Still this Null Pointer Error is shown in the console when changing Worlds:

@gunleader Can you show me your worlds.yml file?

Sorry for the delay, here is my worlds.yml file: https://pastebin.com/b3b2QM9b

@gunleader You have some incorrect spacing in your config file, which is probably breaking YAML.
