I got 2 major and blocking bugs with Hearts and Minds dungeon.
- If you die after Mordremoth breaks the floor the first time, the floor don’t respawn, the first rift cannot be reached then.
- When Mordremoth became invincible (when the huge wave of mobs pops), the rift doesn’t work on him.
Don’t bother to do that quest since it’s not fixed. A fix is required soon, a lot of players are blocked at this.
