Notification or trade expiration when items in a trade start to rot

Hi!

So it's been a few times that I get a notification "this item rot away". I know I didn't have any food item with less than 4 days remaining in my hoard, so it's gotta be items that I put in a trade (that then don't show in the hoard). If I had known they would rot, I'd have salvaged them to get bones, but I have a dozen trades going on at any given moment so I'm not gonna manually check each of them. Also, I feel uncomfortable selling people food that could make their wolves sick (most people check expiration date before buying, but some forget), so if I had known I would have removed it from sale.

So I think it'd be useful to get a notification when an item in a trade starts to rot, or have the trade expire automatically on the start of the last day of its durability, as long as it's been put in a trade before that day.

It would only necessitate a few tweaks in coding.

Thanks, have a good day :)
