I lost 1350 while using the market, and JacaRoe has told me that it's due to a login error. The screenshots are shown in the attached files
Every time I get a report on these issues, I'm recommending they post a screenshot of their market history. I did this also, thinking it might assist in zeroing in on whatever issue is causing this. I realize Lucid is working on this as well, and I will gladly help as much as I can to get this resolved.
