Hi, I am creating a modpack and was testing out mods and yours worked, the castles spawn, the sound in the beginning (can you add a config option to disable that btw). But when I tried to tp to the dimension, I crashed. I'm using the newest version for 1.12

Any help is appreciated. Thank you!

The fix and the config option will be in a build tonight.
Thanks for the report! :)
