Same issue here. And also there are loots suppose to drop at Phase 6 now droping at Phase 5. They must have done something wrong messing up with the loot system. The dark runes used to drop from the summoning room and the room after it from adds. Now I have done 5 runs there are no more dark runes drop from those mobs anymore. Instead they are now droping for the 6 mini bosses which is terriblly wrong
