Alright, so this is the second time this has occurred with me but this session was particularly bad, as there were four different times when a nightmare would still be near their spawn/still in spawn (no where NEAR the sacrificial portal) and they would suddenly just dematerialize and we’d get the “nightmare sacrifice, -10 seconds.” As someone who already is having trouble getting the god damn alter shell (literally the only thing I need to complete harbinger, but 260+ waves in and nothing) it’s infuriating when we fail an encounter because of this glitch. PS4/6 people present in lobby.
