Note on 1.14.x : Those builds are early alphas. Bugs are to be expected... Please report them on Github's issue tracker! If upgrading to build 32 from an older build, please delete your config/undergroundbiomes folder!


If you have a problem or feature request, please use Github's Issue Tracker, I'm more likely to react to that in a timely manner. If are wondering why so many versions were skipped, you may find them here. You may also contact me trough my discord.
