Mythic Botany biomes won't generate, unsure of the mod that caused the conflict.

Version: 1.8.2

The mods used are:

The biomes won't spawn in the server, or my own private worlds. Have used the locate command so many times and couldn't find a single biome in the overworld.

MythicBotany does not add any biomes to the overworld. The biomes added by MythicBotany all generate in the Alfheim dimension.

I thought you can't get to alfheim and the portal only transfers items, how do I go to alfheim?

You need to drink from the mead of kvasir. After that, you can go through the portal.
