Say you have the metastore enabled (default behavior), and copied over the cache for a layer from another server.
Can't copy the metastore over because it contains different layers.
So when a request is made for a tile that now exists in the blob store but doesn't in the metastore, the metastore will prevent the tile from being served, even if there's no expiration rules set (the reason why the metastore is being queried at all).

Make it so that the blobstore is asked for the tile anyways and if it exists it is returned if no expiration rules are set.
