We had a huge wind storm a couple of years ago. Well about 2 hours before the wind picked up, I began playing through episode 2 of Phantasy Star Online, preparing to begin my crawl through the Sea Lab on Hard. So I gained about 5 or 6 levels, picked up a ton of loot, and died about ten times, but eventually I managed to get to the boss. Finished the fight down the elevator and was pretty dang close to finishing Olga Flow off until... nothing. The screen went black, the room started to get really warm, and I was about ready to scream.
For those of you unfamiliar with PSO, saving requires quitting, and quitting during a dungeon resets your progress within that dungeon.
