Preventing accidental silly sales to vendors

Please may I ask that you put in a confirmation dialog when a player is making an absurd trade - namely accepting a scroll fragment for a 20% Vaal gem

This is probably the third time thus has happened but it is very easy to do, for some reason my “auto level disabled” got disengaged on my 20% fall molten shell level 13 gem and I accidentally overleveled it 2 levels, I put into vendor with a 2 scours and as one does you just instinctively hit “A” . This is the point where I discover that you can’t double delevel a gem....
so I lose 2 scours and my valuable gem

Please put in an “are you sure” dialog anytime a trade will result in only scroll fragments - in playing on xbox since Sep 2017 I don’t think I have EVER intentionally made a trade for scroll fragments except possibly at the very start of a character

It wont help, you will be pressing 'a' during "are you sure" window too lol
