It's mostly a pain to see that as you are the last one in the lobby when there is almost a full one. Such as like there's 15/16 players and it zooms down to 1/16. It's really upsetting and sad. They left the fun to you, sort of. And nobody can play alone in minecraft. I hope everyone can still have fun that way. Of course you might be thinking, "Maybe they just moved to another lobby." that could be a possibility. I just wanted to point out because it's annoying when you're the only one when the game has like, 3 seconds left to start.
