I've been trying to add to an event that fires when an existing recipe is fired (Butcher Small Animal), but it doesn't seem to ever get called. I see in the Javadocs and a few comments here and there that this function as been deprecated. What is the replacement to know when an existing recipe is completed?
I know how to use the OnCreate field for new recipes I'm defining, but I want to add some additional logic to the built in ones without having to hijack and overwrite the existing function.
