This is the main mod file. I assumed that onBiomeLoading is not being called. But I still did not understand why it was not called. Tried making the method static, but then an exception is thrown (java.lang.IllegalArgumentException: Method public static void has @SubscribeEvent annotation, but takes an argument that is not a subtype of the base type interface net.minecraftforge.fml.event.lifecycle.IModBusEvent: class net.minecraftforge.event.world.BiomeLoadingEvent). Tell me what I'm doing wrong. Thanks!

• Specify your ModID when using @EventBusSubscriber.
• BiomeLoadingEvent is fired on the forge event bus, not the mod event bus.

Is this how it should be? But the method is still not called

@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.FORGE)

This is the updated code (as I understood it needed to be changed).

Now you are using the forge event bus, but RegistryEvent.Register and FMLCommonSetupEvent fire on the mod event bus. You need separate event handlers for both.

Your onBiomeLoading method is also still not static, meaning @EventBusSubscriber will not register it.

It helped, thank you!
