Heres a crash report:
crash-2018-06-21_02.36.55-client.txt

says something about noppes custom npcs scripted item and an amulet blacklist. I'm supposing the custom npc item is just incompatible with it. Since I know JEI goes nuts at it as well, but thankfully it can be blacklisted off of jei so it doesn't keep blowing up.
