So I have only been having this issue since ~0300 PST when I tried to open the PvP panel in the PvP lobby to leave said lobby, on clicking the button - Crash.
Likewise I then logged back in and hopped to amnytas(sp?) hopped on my skyscale, then started climbing, I was in an updraft when I turned the camera, skyscaleface -> freeze -> Desktop
edit: was trying to navigate with skyscale through the animated museum exhibit event, crash.
