Game just disappeared from schedule
 

I had a three game series against Cleveland. First two were split - hit the button to sim the day and...poof..game three of the series is gone, never played and gone from schedule. I manually counted all the games and I have 161 instead of 162.

Most likely the 3rd game was rescheduled as a double-header. I'd suggest going through the sched again - sometimes the extra game can "hide" on you a little.
