Champions Disappearing
First game, I got an Ashe with Deathcap. In the round against Krugs, my Ashe and Deathcap disappeared and another Champ was automatically put into the game.
Second game, I had a Vayne with PD, HTGB, and BT. It was against Drake and I really needed items, but my Vayne disappeared and was replaced with a lvl 2 Darius. Items all disappeared as well. I lost that round, then lost the game in general...don't know if it would've made a difference, but I was pretty upset because the Vayne was my only carry (besides a lvl 2 Lucian with Tear lol).
