[1.12][BUG][UI] Weight is not updated when you leaf through a group of champions to trade/shop items
You have a group of (or containing some) champions and open the shop/trade window. Then you navigate to the next champion using the small arrows. His/her weight and encumbrance are not updated unless you unequip and equip some item.
This is a small but very annoying issue. You decide to buy an item for this champion to give some benefit without increasing the encumbrance - only to realize afterwards that your calculation was based on the data of a different champion.
Sorry, this is not the normal behavior as I thought. (Only the weight of the second champion on the trade screen, who takes the place of the shopkeeper, is not updated, but this is much less of a problem.) There is no use looking into this unless I can reproduce and document the behavior.
EDIT: The observation was valid, but not in this generality. See below.
