You have to adjust your config.yml if you want to change something of the new features(or you can just generate a new config.yml). This are the new entries:
Code (Text):
Messages:
no_number: '&cThis is not a valid number.'
added_extra_home: '&aExtra home successfully added.'
removed_extra_home: '&aExtra home successfully removed.'
set_extra_home: '&aExtra home successfully set.'
info_homes: '&9{player} &ahas actual &9{total_homes} &ahomes and is able to create &9{extra_homes} &aextra homes over the limit(this also applies to permission limits).'
On the main page you can see how the config.yml should look like now.
