Well, nothing besides a "reset upgrades" button, although I think that might have been there before. It's bad enough that maxing everything requires more than 4 times as many eggs as the campaign contains. I really wish I hadn't wasted so much of my energy on this, consider it a PSA to warn others against doing the same.
