The statistic "Games quit" doesn't count up if you leave the world. It stays at the position before the snapshots. Same case therefor for the stat.leaveGame criteriaType.

What I expected to happen was ...:
That the score count up every time you click the "Save and Quit to Title" Button.

What actually happened was...:
The score stayed at it's last count before the snapshots.

Steps to Reproduce:
1.Open any world
2.Open Statistics
3.Remember the number behind "Games quit"
4.leave the world via pressing the "Save and Quit to Title" Button
5.Open the world again
6.Revisit the Statistics
7.Compare the old with the new "Games quit" score.
