In the current build, it is not possible to select food item from a refrigerator any more.
This was possible in OC.
For example, if a refrigerator contains several items and one of them is contaminated or nearly rotten, it was possible to select it and then press "Compost" to take it out of the fridge and have it taken to compost or to another fridge for decontamination.
This should work again, otherwise it will be nearly impossible to separate contaminated or stale food from fresh, non-contaminated food.
select a fridge that is not empty, try to select an item from the list of contents
