I'm sorry about this. The programming limits the number of favorites you can have, but I'll look into whether this can be modified.
If you go to Photos, do the search for some of the items you discriped, you may be able to find it. If they are tagged correctly it should come up. I have to tag some of mine still but, I just did that with calla lillies and I got 4 cakes that came up. It may help to find the cake again.
