DS Daily: Corruptions, bugs, and glitches

Recently, this blogger had the displeasure of losing all her data in Geometry Wars: Galaxies. One minute we were best buddies, inseparable and joined at the hip; in just an instant, however, the save data became corrupt and everything was lost. All unlocked galaxies and drone level-ups were gone, along with high scores and gold medals. Instead of starting over, Geometry Wars has remained untouched ever since.

Have you ever lost your data in a DS game? And if you haven't faced corruptions, have you played any games that had bugs or glitches that made you want to stop playing? Even better, have you experienced any funny glitches in your games?

Or, has your time on the DS managed to be bug and problem free? If so, we envy you!
