The missing Loot dragon means the friend that had that dragon, now has a different dragon as their available co-op breeding dragon.

Someone correct me if I'm wrong about this but I believe once you choose your own dragon to breed with while in the Co-Op Cave Dragon list, the game automatically make that your "preferred" co-op dragon. If you don't want to keep that dragon as your co-op dragon you can then click on any habitat and make a different dragon your co-op dragon by toggling the blue heart.
