We start a custom game. We finish one game and then it skips all the rounds and ends the game. You sit in a loading screen until all rounds are done. We tried restarting, choosing a different game mode, and hard resetting. Nothing works and I am disappointed as I love custom game 
This seems to happen a lot with Infection-based game modes.
Infection has been broken since release. This latest update broke it even further. Still waiting for fixes from months ago, and with new ones present it doesn’t seem like we’ll be getting them any time soon.
