I've been having this problem, too. And it still remains here, and actually it is happening to me real frequent, in every 2 minutes or so I see 'R0'. It was happening before the last maintenance and it still happens after that. Guess it is not our connection, since we all connect from a huge variety of countries with different ISS and router/modems. This has to be their server issues. And they should find a solution asap cuz this is completely killing will to play, at least it does for me.
