If you get two winners of the audience vote, no matter the composition, you encountered this special bug. Easiest way around it is using an earlier save, best from around update ch.3/up.2 and speedrun through ch3/4 public again. This should set the variables right.Am I right to understand that this is a bug and I have to rerun (via Ctrl) the "Ch3 Up4 Public" content before starting to play Ch4 Up1? Thanks.
Btw, a draw is still a possible outcome even without the bug, depends on your choices if that happens.
