Crux of nothingness bug

So I did the King of the Mist and after doing the first phase I went to the realm where you chase the spirits and find the exit and once I went through the portal at the end I walked up to the King of the Mist and he was just frozen in time. I sat next to him for about 5 minutes and he never phased. I took a screenshot for reference



Hope this helps!

Also if you need me to send log files or anything I can just let me know. This happened between 11.25AM and 11.35AM EST time
