It is a glitch in the map vote reporting system. It may be fixed in one of the updates coming over the next week. If not I will look into it more and try a direct fix for it. Also as work on the new wcs steps up over the next few weeks other issues will take a bit of a back burner for a time. However I plan to create issue sticky threads for all of the servers like we have for the zm right now, to help track updates and requests for fixes.
