This is on the PC version. My connection was a bit laggy at the time too.
Not sure if this is a reoccurring or rare bug but it happened during a Ravana Extreme fight.

I died during Final Liberation and raised right after when it did the donut then center AoE attack. At the time of the screenshot that's when Ravana was in the warlord shield.
I tried clicking the enemy list but it wont target and I tried click on my teammate but there's not target of target, as you see on the second screenshot.

My guess is that I raised when Ravana was in transition from disappearing and reappearing, which somewhat my client wasn't registering and recognizing it to reappear. Ravana did reappear after he dissappear and reappear when switching stance. (Red phase/ or Readying for "Liberation")
