I was playing classic a few minutes ago, and the UI bugged out. This only happened once, so I don't have steps to reproduce it.
I was in the lobby, and I think my connection lagged. There were around 12-13 people, and it was stuck at that, so I decided to leave.
I clicked on Leave but then I suddenly ended up at the Role selection wheel and then suddenly to the end of day 1 in-game.
