Autolosing when buying champion mid-fight.
Just as I was about to win the round I decided to buy Poppy for the next round just in case I got more Yordles. After buying her, all my units died while close to full health. I have no idea how this happened. As an extra note, I lost the round against the wolves. P.S. Sorry for the quality I don't know why the quality of TFT is lower than what I usually capture.
