Infested dont run out of their spawn room

[(XBOX)oD Static]

Just now i played Seimeni on Ceres. After round 10, a host migration. Round 11, infested don't run out of their spawn rooms unless being approached. 5 Round of running from spawn room to spawn room to kill them. At first i even thought they wouldn't spawn at all.

I'm having this problem right now on PS4. It seems like the same bug as this PC player had: https://forums.warframe.com/topic/787011-infested-enemies-stopped-attacking-cryopod-after-a-lag/

I've had this happen twice in a row on Akkad. I was playing as Chroma both times, with different groups. It started on wave 13 the first time, and we were able to go kill the enemies and eventually extract. The second time, the issue started at wave 11, and we ended up aborting the mission. There were no lag spikes or host migrations either time.

I've done several more missions and extracted after 5 or 10 waves and haven't seen the issue happen.
