Anyone else having this problem since Summer 13? When I refresh our Sandbox it only copies over our Custom price books but not the Standard one. Naturally this makes some of my (fully working in Production) code just die. To top it off, you can't actually create a Standard pricebook.
It started happening immediately after Summer 13 was released (where they "promoted" the Pricebook object) so I assume I can't be the only victim.
Anyone figure out a workaround?
