Mark of Rift (In Your Heart Shall Burn) bug, Can't progress
(System PS4, fully updated game) At the end of the In Your Heart Shall Burn quest, after defeating the boss, I end up in a cave. As I move forward, there is a Mark of Rift tutorial. I press square and try to use it, but my character died too early. Now, whenever I reload and attempt the same thing, I'm not even able to use the Mark of Rift and my character keeps dying. If the previous fight wasn't so hard (I did it on Nightmare difficulty at a lower level), I might've reloaded. But I really don't want to have to do that all over again, with the possibility that this might happen again. Any suggestions?
