Would it be possible for you guys to support custom worlds like Twilight Forest since it has the folder name DIM7 and not 1 or -1?

Example 1: /wb worldname DIMxy fill
Example 2: Let the plugin search through the world folder for folders starting with "DIM"

I just added some lines of code by myself to get it working on my server so there is no rush.

Hopefully addressed by this:

Thanks for looking into that :)
Will try it later.
