TrialMaster Fight Flight

Thunderous Leap entering into Trial Master arena - he time stopped during the animation. At the end of his time stop animation I was then TELEPORTED/ZOOMED across the screen for several seconds and placed in a holding area? like a sub map of the same zone where assets are stored or something and I was stuck in the wall there. Was able to cast spells/skills and dodge roll in place etc. but couldn't teleport out and cannot warp or use other means since it is an arena. Boss music continued but was so far away I coudldn't hear anything he was doing. I did submit /bug but lost the clipboard paste when I took a screen shot without thinking.
