Itens change order when selling an item, so if you press to sell too quickly you might sell something important >.>
was selling a bunch of itens and the inventory reorganized several times mid trade, it was a very intense experience to no sell my beloved knifes by mistake
3 months later this problem still exists.
yep getting pretty annoying 
It’s always super intense to sell, because the game tries to make you sell your best gear, and it’s just 1 button click. Boom. Gone.
Moon just invented a new way of padding play time, hahaha
Thank you for the report. I have re-escalated this issue with the Ui department
