My Unit Became an Enemy

While playing tft just now I had a little lag spike as I was selling my units. I had 2 aatrox one sold fine the other wouldn't sell for some reason. eventually I put it on the board to see if it would fix the issue. during the next round he started attacking my units immediately and had a red health bar. i took him off the board and was unable to sell him and he had a red health bar while i was not in the fighting phases. funnily enough I was even able to level him up.

hopefully no more champions go rouge in future
