When a can is opened with the can opener, the food moves from it' current slot to a different slot.
For example, if I have a can of beans in my backpack and open it with the can opener, the beans disappear from the backpack and an open can appears in an empty slot in my cargo pants.
If, however, the cargo pants are full before opening the can of beans, the opened can of beans stay in the back pack.
This behavior is inconsistent. The opened can of beans should appear in the same slot as the unopened can of beans for all cases. {F28694}
