[1.12] NullPointerException populating the SearchTree in Modder Support Posted December 1, 2017 · Edited December 1, 2017 by TheA13X 12 hours ago, XFactHD said: [...] registry events are fired before the FMLPreInitializationEvent.

Also if the Registry Events were fired before the lists are populated, there would be no exception in the first place.
