so i finished the 2 horde mode arenas in the house of reckoning mission and then i die in the 3rd area against the elite boss and i get reset to first arena room but no enemies spawn and lets me walk to entrance to the 2nd arena again no enemies spawn in the 2nd arena like in the first room and i click the down button to show me where to go and tells just go to the exit and straight to the elite boss but the door isn’t open so it wont allow to progress is anyone else having this issue and whats a solution other than restarting the mission
