When destroyed by taking damage (e.g. by volcano rocks), a cargo boat does not drop its contents. This can be a major problem if, for example, you leave a cargo boat by the shore with the fishbone in it; the fishbone will be permanently destroyed.
Steps to Reproduce
Spawn a cargoboat, and get the fishbone (or any other item that's floatable). Place the floatable item in the cargo boat, give yourself a volcano staff, and summon volcano rocks on the cargo boat. It will be destroyed and drop part of its recipe, but none of the items inside.
