Hi,
I noticed this behaviour.
My character had a "bread" x1 in inventory.
In the container i'm looting, there is one bread (x1).
I click on it to take it, hear the "tuhmp" sound.
In inventory, still x1 bread.
Changing character and back to this one. Bread is now x2.
I did the same with my wizard. he has "astralagus" x7 inin ventory. 1 in container. Clicking.
Still x7 in inventory showed.
Back and forth? now it's x8 in inventory.
I assume the multiplier should adapt immediatly to avoid confusion.
