Put the blocks for create arc furnace in crate and put crate in world cause crash... Maybe? It's just random crash which can't be repeated the first time.

I can not replicate this issue.
Have you had it happen again, or was this a one time thing?

No. Just one-two times. The only thing I can say is that the box had a different hitbox when the parts of furnace were put in it.
