As neither in game GMs or Customer Support are responding to my ticket I will try the forums.
Yesterday I have noticed that one of my characters (the rest are fine) is not getting any xp. I have run Elite Shadow Crypt and even tho in game message said of 49k xp none has been added. Same after hard run Jungles of Khyber - 24k xp down the drain. I have relogged and restarted the client couple of times, I have tried some explorers - all with the same end-result the xp bar is stuck at 1 538 769 xp( almost half way through rank 61).
Since there is no point playing my main character I have cancelled my subscription but I am trying to find out if anyone had or heard of a similar bug and could maybe offer some advice.
