Assembled products don't display items

[BeDepraved]

When using spree_product_assembly the invoice only shows the assembled product. Not what actually goes into the bundle.

I'm sure this can be corrected with some editing and I'm trying to figure it out on my own. But I figure maybe someone has figured this out. Also this would be handy to have built in. When/if I figure this out I'll post my solution. I hope someone else has the solution already to be honest!
