Ensure the animal slaughtered is synchronised #179
Description
Currently on the animal slaughtered is guranteed and tested to be in synchronised between animal and the meat.
However, we need to also ensure the animal slaughtered is synchronised with the non-meat item.
The reason for the de-synchronisation is due to the fact that only the animal slaughtered is passed down from animal to non-meat items but not the reverse. Maybe this should be implemented.
