There should be more information on how to use mods with custom world types. For example, Biomes O Plenty's world type is something different than Biome's O Plenty. I still don't know how to make my server have the Terra 1 to 1 world type. Any help on this? Also, for custom world types, there should be an option to see the details like how to get the custom world type.
Thanks for reading.
(Please help on the Terra 1 to 1 world type as well)
