Empire has been very kind and has totally remade the whole generation system. We now support third-party generators and allow them to supply us with IDs/Functions. This will allow for some extreme customization.

The new UUID system will allow you to use UUIDs of players that haven't been on the server (helpers, trusted, deny, setowner etc...) is both faster and more efficient than the old system we had.
