I consider the following as a big flaw:
I went to a trader and saw there was a bag available, so I decided to sell one of my 2 pouches to get the bigger bag. When I sold it, the 3 items that were inthe pouch vanished. I didn't sell them, or want to, and couldn't recover them. They were worth more than 8SP at level7!! Really annoying. Maybe the stuff fell down, but I didn't check.
One shouldn't be able to sell a bag or pouch unless it's empty.
