In my mod I have several custom flower types (instances of FlowerBlock), which I register using the DeferredRegister. Now I want to add them to the composter's registry of compostable items. I know I need to add them to ComposterBlock.CHANCES, but I don't know when exactly I need to do this. When I call ComposterBlock.CHANCES.put() in my mod's main class's constructor, I get a NullPointerException with the message 'Registry Object not present: my_mod:my_flower', even though I created the flower objects before I tried to register them. I suspect I need to call this at a later time, but I couldn't find any information about this anywhere.

Maybe try using FMLCommonSetupEvent to do the call to put() instead of main constructor.

That did the trick! Thank you so much!

Good point. Thanks!
