This just happened to me in Champs on PC as well. I could only control one player. The opponent looked like they knew what was happening and was trying their best to score. I didn't want to manually quit because I wasn't sure if I would lose an attempt, but after they scored 2 I did quit.
I also didn't see a triangle over my opponents players.
What is the best solution? To stay in the game in the hope that the anti-cheat recognises a cheat and kicks them out?
There is no anti cheat in this game :D
If someone somehow handle to start the game - anticheat can do nothing about what he's doing
