Had this issue with a pack in the Storm Halls. Two of the minions came up out of the ground, attacked with their leader, and died after the leader died. Two minions stayed in the ground,, then popped up to fight after the leader was dead. They remained invulnerable
Edit: Spent about 10 mins in other parts of the dungeon and they despawned. Also took a death before going back to the invuln minions' location
