I've entered game data for five games and then look at reports, e.g., pitching, and it comes back with a great report. I then save and re-open and get nothing in the report, although all the data is still there, as it calculates, e.g., ERA for each game - just no individual stats. Same goes for box scores - data is there but it won't produce a box score for game(s).
This issue has been fixed in version 3.3.
