Turns out this is random.

Redid it and it did not die.

commented

i know there is a npe associated, but is there a stacktrace for the cme?

commented

The only related stack trace is the generic one from Minecraft. All the other ones in the log are handled and do not cause the game to crash, mostly related to compatibility with two other mods. Those would not be related to this one.
