I don’t really have any screenshots, but I have had it happen a two times now.
I ran the Temporal dungeon. As I was fighting the boss, I spammed the time shift multiple times. After that, I was taken down to 0 health several times, but I didn’t die. The only other option that could be is teleporting out of the eternity cache room. I will attempt to continue testing this an take screenshots. Also, this is happening in offline play.
