See the Voidweaver GitHub for the complete changelog.
Added a config file, as well as a check to see if a dimension has been created prior to allowing you to jump to it. You can now blacklist namespaces (like minecraft) so that you don't accidentally prevent a dimension from being generated that you may want in your playthrough.
Enjoy!
This version embeds Fantasy v0.5.0+1.20.4 so that there is no need to install separately. If you have issues with this version, try installing 1.1.0 of Voidweaver and install Fantasy manually as described.
Requires Fantasy v0.5.0+1.20.4 in order to work. Be sure to download this to your mods folder!
