saddle bags not updating inventory

[Oblivionnreaver 5,175]

every now and again, a saddlebags menu from "open saddle bags" will stop updating, you can drag and drop items in and out still, but the actual panel won't update and will still show items in there if you dragged them out, or nothing if you dragged them in. have to close and reopen it for it to start updating again. seems to be much more common on a ridden horse compared to a led horse.
