Thanks again for the previous fix! Hopefully this will be the last time I bother you guys!

When I tried creating a new world for Nevermine and Divine RPG, I get the following error. I'm not sure what's causing it.

This looks like a DataWatcher ID conflict. DivineRPG uses 27 and 28 for the AracanaBar.
To fix it for now, there is a config file option to change the DataWatcher IDs for Nevermine.

We might still adjust the default values we are using and/or make it a config file option also.

Wow, thanks again! I switched the DataWatcher ID's and everything works fine!

I think we should change the default IDs and add a config file option for these, since it is such a limited resource.
