It seems like the Mousekeeping staff at BLT has this problem. We had the same exact experience last December, except the discarded items were my my daughter's wedding cake, crystal cuffs, floral bouquet and a couple of other things.
Here is my post about the subject:

The mousekeeping adventure starts at post #83, but the part before that was a lot more enjoyable.
We spoke to everyone we could find, sent letters, called various peole after we got home, spoke with
DVC brass, etc. After a few months of discussions, we received a small monetary credit for my daughters next visit and a new cake top which they could not ship home...... but never an apology or any admission of wrongdoing by the mousekeeping staff.
Hard to believe it is almost a year ago............
