Since I have installed this mod I have had this error thrown at me that I have never encountered before. It is an issue with Biome IDs. Is there a way to fix this or is it an issue with the mod or..? :

EDIT: Could be an issue with Journey Map as I opened the map and then the crash happened...

EDIT: Tried it again and map works fine. weird.

Same Here. Odd... Seems to work fine most of the time then I get this random crash.
