I sincirely apologize for the rush of updates however this is a very important change to the config.yml + lang.yml
all the formats in the config and lang yml's have been changed from
World Type: to world_type e.t.c
This is simply to ensure that the yml files won't break during an update and to also make it easy for me to use the files into the actual plugin.
If it's easy for you please reset both of your files or simply replace all the values on your config.yml to no caps with _ instead of space and simply Reset your lang.yml
