I have the same problem. This session i checked immedeatly after anytime someone chose to cash-out, the hand did not come up in the active session or any data. It's like the hand never happened.
Very big problem for me since all my graphs are useles, all the hands that went allin and somebody chose cash-out, are non-existent for HM2.
I am very bad with computers so i cannot find these hands and upload them into a zit-file for you, hopefully the team can still resolve this problem.
