Nope, but I've been sent back to lobby without any error message before. It usually happens when I'm AFK or even at my desk but alt-tabbing out to read something else. I would be dropped from the game and sent to lobby when I looked back to D2.
And I've been having connection interrupted and got kicked from the game. WHen that happens, the game would be gone, no more existing, even though I immediately rejioned and the game was up for so long that it's already perm.
This problem has been happening since the past 3 days.
