This is probably already mentioned in another thread, but I'll still tell ya. Click the pack that you play on. Next click edit mod pack. After doing that, click biomes a plenty on the right side of the screen, then click enable. Exit out I'd the edit mod pack screen and launch your game. Congrats. You. Are. Done. If it works, I would appreciate a like. Have a great day
