End of game scoring

[batesmotel]

On my opponent's last turn of a game I expected to lose since i was already at 59%, I think my opponent broke one more of my knights as nothing else as I recall from the replay, but my lost percentage suddenly jumped to 67%. Is there any way that one unit should have ben worth 8% of my army or to review if I lost something else on that turn now that the game is completed?
