I was playing after hard day of work and I totally went on autopilot for 30 min. And then it struck me. I was selling currency I found on map instead of stashing it. Yeah, I know.
But vendor UI in PoE 1 has a visual warring, you always see what you are selling. In PoE 2 selling with ctrl, doesn't bring you to Buyback screen.
Maybe it should. As a safeguard from... tired people.
