Hey everyone. Just wanted to put up a quick note that we are actively investigating the issue with getting stuck unable to queue up for PvP matches. This bug is something that would come up occasionally in the past.
A bit of simplified explanation: For a currently unknown reason, players are sometimes not removed from the roster (group) they were in during a PvP match. Then, when you try to queue up, the system sees that you're in an active roster and decides to do nothing. As this used to be somewhat rare, we created some scripts that comb the system looking for old rosters and clear them out, which would fix the problem. These scripts can only be run so often and against rosters of a certain age, since the automated tournament system keeps players in the same roster for longer periods and we don't want to destroy those rosters.
In the last 2-3 weeks, the frequency of this bug has gone up dramatically and we're not sure why, though we have some thoughts on ways to work around it. We're currently in the process of building some additional logging to further help us track down the issue.
We understand that this is extremely frustrating, it is for us as well. We'll keep you updated as we get more information.
