I get a NullPointerException in CommonEventHandler.java:133 crashing the game when trying to apply the Elytra upgrade to an EnderIO End Chest in an Open Blocks Auto Anvil. Using a non bauble regular Elytra.

This is in Enigmatica2 Expert 1.53 using

• colytra-1.12.2-1.1.0.2
• EnderIO-1.12.2-5.0.39
• OpenBlocks-1.12.2-1.8

colytra.cfg has an empty blacklist
