Hello, I'm playing in a modded server, it has the "FTB Unleashed" mod pack and it has the biomes o' plenty mod, I want to play with that world generation and I looked for a tutorial and I found here that you must type "BIOMESOP" in the level-type when generating a world.
I tried it 5 times and it didn't work, I even tried importing a world but only the loaded chunks were Biomes O' Plenty, the new chunks were normal so I want to know if this is a bug or you can't actually play with this mod.
Thanks
