I've got a Google Calendar for the baseball team I like. (Hint, every MLB team has an iCal link which can be imported into Google Calendar: click on your team name here, go and then pick downloadable calendar from the left side bar, and copy the iCal link to Google's public calendar import.)

Obviously, the games are always at the same time, so that never changes, but on Google, they're updated with the score during and after the game. This changes in both the Event Name and in the description. However, the Pre just totally ignores any changes there.

I'm not sure if that's a bug or by design, but it needs to be fixed.
