[21:24:12] [main/WARN] [FML]: Found FMLCorePluginContainsFMLMod marker in HammerLib-1.12.2-2.0.6.26.jar. This is not recommended, @Mods should be in a separate jar from the coremod.
What to do? and what to type in World-Worldtype for Biomes O'Plenty Generation? If someone answered about Biomes O'Plenty don't ↑answer to this question again. Mainly I want help with that HimmerLib.
