I don't recall what she titled it, but it involved her first original character, Nena Ashley (an expy of Nena Trinity and Lockon Stratos from Gundam 00). When the other authors flipped out, it got so bad that the mods had to step in and remove all the posts. The worst part is, they only calmed down and explained why it wouldn't work AFTER she'd gotten so upset she killed the fic... and then shortly afterwards, someone came in with practically the same fic idea and it was accepted by the same people who had shunned her.
For more details you'd probably have to ask Synae herself about it. Dunno if it's still a touchy subject for her or not though.
