Oh, thank God! I finished about half an hour ago, but while I was scrambling it to submit, my computer froze and I had to restart. Unfortunately, I ended up saving the scrambled version over the right one. I just managed to get my original back. Luckily only the first half had been scrambled, so I didn't lose anything.
Now I can actually celebrate!
(I did kind of cheat, though, since it's not all one story. I wrote part of a story, and then a bunch of one-shots.)
