Did they change Stonehenge this week?

I’ve been doing it solo since it came out, was doing wave 15 comfortably as of last week… now it’s much harder. I don’t remember Commanders spawning at wave 15, but now they do, and I barely get the anomalies anymore.
I noticed the change late last week.
Am I just REALLY unlucky?

Yes. You are just unlucky.
The game is the same since the last patch which was on the 8th of april.

They haven’t changed anything in months, let alone OD.
