I have had this issue for a very long time and repeated tickets to kabam only say programmers have been alerted and are looking into it. I can not switch any realms at all unless I force input the exact realm number in Internet Explorer through Kabam site. Chrom seems to work on either facebook and kabam for all kabam games except Kingdoms of camelot. But Internet Explorer does not ever let you switch realms through Kamab site at all without forcing by realm number every time you want to switch. This issues is same for any Kabam site game and is more than annoying if you do not have or want to always have to run chrome for kabam site games.
