When taking a small carriable item/object*1 out of a Cart or Boat *2 the decay color on the item shows*3 as undamaged/new for damaged items.
1) Birch-bark Basket in this case. But probably for all containers, or even all items that can be put in a Cart/Boat type object.
2) Only have Cart or Boat, Assuming same for others travel objects.
3) Reset to correct color after at least a area refresh. (house exit.)
3) Color only, Decay value on container is maintained/correct. (obvious, as otherwise it would not reset back to normal.)
