Missing Piece

So I finished my Halloween puzzle and dam I am missing a piece. And right in the middle of it.

This is a CEACO puzzle and I don't know what their policy is about missing pieces. Does anyone know? And is this something the puzzle Dr. can replace. There is a lot of detail in this piece.

Makes me want to start counting pieces before I start from now on. I understand if this was a thrift store buy but it was purchased new.

Any suggestions??
