Official automated sim matches loop, and sometimes the loop desyncs and you have one lobby for two separate matches.
The solution is to wait for server restart, or play player-made rooms.
On the topic of empty servers. A couple of days ago i encountered two different server that were filled with “afk” players without any actual players. And they were both in a loop where game started because the lobby was filled with like 20 players but when the game started everyone was greyed out, so the game ended and went back to the lobby again. This went on for a few hours, just a server with no players starting a new game every 5min. Spooky
This one, is special… If it genuinely locks you into a cycle of joining and leaving the same match, then you’d be able to demonstrate the instance of this happening and highlight the impact of having it happen.
It’d literally be a critical level bug that would literally be fast tracked…
