public class FMLModIdMappingEvent
extends FMLEvent
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.
