Original? more like a riposte

That happened to me once. Wrote a long ass story called "League of Legends: Apocalypse." It was a narrative story told from the perspective of Graves, and it dealt with an alternate timeline where the Void army attacked, and destroyed the Institute of War. So Runeterra's factions had to create an army of the champions of the League, though not all were present. So, just before the battle starts the army from the Shadow Isles invades, causing a third group to appear. So the human/Yordle army gets decimated and the Void and Shadow Isles battle each other for control, as the remaining survivors try to survive in the apocalyptic future. Took me about an hour to right. Hit backspace once, and it sent me to the previous page and erased all my story... fucking hell...
