Having been victimized myself by this issue, I can add this:
If someone bails out of a game and causes the game to end early, the bonus points (and probably even the normal points as well) are not added to your totals. The daily play is credited but the points are gone forever. Even if you start and finish another game on the same day, you don't get the bonus points. That is something that WGT could fix if they were interested at all in doing so.
