Okay, only the crafting terminal causes explosions, the pattern one doesn't.
Ooh now I remember why.
I was trying to make something illegal.

I'm guessing sengir screwed that up. Or maybe it's a test recipe that no one else could be as foolish to try.
Either way, could be used for trolling to temporarily lock someone out of their AE I guess.
