Blizzard says the login queue bug is fixed
Blizzard says it found and fixed an issue that was causing the login queue to fill after a disconnect.
Players who hit a login queue right after a disconnect got an answer from Blizzard on the beta forum. Kaivax replied that the team "looked into this, and found an issue that was causing the queue to fill, and we just fixed the issue."
For players, a queue on reconnecting should no longer come from that bug: Blizzard says the fix is already in.
