My character seems to be 'stuck' in instance 'mode' because I can neither send nor receive /tells. This is also happening on my lvl 10 end quest for my story line. When this happened, my game froze and I got kicked for 'Connection' issues. The game couldn't process me both zoning AND the queue popping at the same time. I believe this is when this error happened. I have been receiving this error code (90000) every time I enter a 'Duty' - for both the instance and my story line.
