Dong U Deadsaid: It depletes when you go offline I am sure - Best to read RSwiki - as I am not a hundred per cent sure, but I am pretty sure my food goes down when offline?? I will have to keep an eye on it and see if it does. I know if you don't keep Miscellania maintained you will run out 'flavour' for the workers if you don't log in or lose membership - I am sure this is the way with the farm food as well??
Oh gosh Dong is right. If you have animals in your pens they will still eat the food you put in the troughs for them.
Sorry, I was thinking you meant the compost bins. lol, my bad.
