Fixed in 1.9.0.816

If a hand is received twice by the reviewer from the back end, hand_start_index may grow higher than it should.

There might be other places where the hand_start_index grows too large.

The user reports:
Noted a hand for later from the task bar (just because I can now!!!) Actually it was the olny hand that appeared there as I havent played for a couple of days. Opened up the hand reviewer and didn't see the instanote. Clicked hide immediate folds, which just left the one hand. Clicked the down arrow to see if reviewer would load older hands from history and here I am ;)
