If you think a technical bug or unexpected behavior has occurred, double-check (using John Smith's link). If it doesn't make sense, document what you know, describing what you did, what the expected behavior was, and what actually happened, and send a bug report:
https://www.warzone.com/ReportBug. Once you get a response on the report, if it's not public, it would be helpful to share here for anyone who runs into the same issue.
