So I have plenty of large prey, buried and unburied ones alike and I tend to gift feedings to friends. So here's what the end of my feeding list looks like, all 8-10-15 feedings:

... but when I want to gift food to other packs, these won't show up, not even at the end of the scroll bar:

So even when I'm full of 10-15 feedings prey, the largest ones I can gift are some 5-feeding ones way above these ones.
Not sure if it's a bug but, I don't really know how to manage this. If I want to gift a moose, a water buffalo or an elephant, it seems to be impossible for some reason.
