public class IdMappingEvent extends net.neoforged.bus.api.Event
Called whenever the ID mapping might have changed. If you register for this event, you will be called back whenever the client or server loads an ID set. This includes both when the ID maps are loaded from disk, as well as when the ID maps revert to the initial state.

Note: you cannot change the IDs that have been allocated, but you might want to use this event to update caches or other in-mod artifacts that might be impacted by an ID change.

Fired on the forge bus.
