Bosses: Viper Napuatzi - Minion issues

so ive done it twice act 3 normal and act3 - cruel, and everytime i go inside the shield guys to enter the fight if i die first on the first part of the encounter when she takes alva away and then have to go to checkpoint and try the fight again i always im left with a couple of minions outside the shield guys that go into to place when i pass trough them , there is a way around it ..is before fighting her i have to take socket gem out and put in place fast so they respwan near me or take main weapon out and put it again but it should not work like this ...try it and you will see thank you for the great game so far and happy christmas to all of you guys .
