I had this happen to me mid-mission once, I think the third one I worked on. I already had enough invested in it to want to finish the mission. I had to wing it without actual quotes from the fic-just the major charges.

After that happened, I started making a temporary copy of the fic in Google Docs before I start writing a mission. That makes it easier to write the mission, because I can flip between them easier without having to navigate all the chapters. When I finish completely, I delete it. I do keep checking the original for updates, deletions, or changes.

This fic would be worth a look:

Summary: Amelia was normal girl, then her life change 4ever. She get Geass and face off against powerful rival and evil guy. And she also find love at same time. My first story ever, lol. Enjoy. R&R. Thank u! XD. Lelouch/OC, Schnozel/OC and other pars.

Warning: Has Lady Gaga in it. And she's the Emperor's daughter, with a Geass that allows her to open portals throughout space and time.

Yeah, something like that happened to me just two days ago. I was looking for a specific badfic (also not bad per se, but horrifically messed up), namely 'Once Bitten, Twice Shy', where the standard personality and behavior of members of the xenomorph race was so badly twisted it would have been hilarious, if didn't like xenos so much.

I mean, seriously, can you imagine a runner xenomorph (admittedly of below-average intelligence) chasing its tail like a kyoot lickle puppy, while making funny noises? That's not only stupid, but also totally unnecessary, given the length of said tail. And it just gets better and better.

Anyway, the point is, I was going to put this fic up on Unclaimed Badfic, but, just like yours, it's gone. Can't find it anywhere on the web.

If anyone does know where to find, post me, would ya? Thanks.
