When I used the "PLAY" button to launch, I got a message that I had "Failed to Find a Match". However, attempting to hit "Play" again told me my current mech was "in a match".
Logging out of game and back in, I now saw the "Rejoin" button over my mech. Only about half the players on each team made in back into the match. There were massive spawn kills of unpiloted mechs.
Hope this was an isoliated incident and not a new bug....
EDIT - other players have posted similar problems
