Updating Cosmos and even downloading the newest version of Census indepently proved to be no solution to the problem.
Am I doing something wrong ? ... or is this 'working as intended' (as in 'you shouldn't take data for more than one faction, idiot') ... or an actual bug that could use a fix ?
It's even more sad as a Horde survey for my server (Hyjal) is currently on the most-wanted-list ... and I'd hate to scrap my collected data on Alliance, which, btw, has not been updated into the DB even though I uploaded a copies every few days for the past week and a half

before I forget it, version is listed as 2.1
