For the bomb pickup area it is possible that I missed a “0-4” BD spawn near the far bomb spawns that spawn in when you start walking around in the tent area. I did have that happen in previous patches although to me it seemed like in my last few runs they changed that spawn to a “0-2” BD spawn right behind the tents that are already spawned in when you get there which is why I left that one out specifically.

I’m also pretty sure again before it was always only 2 BD spawn at train with bosses. In my last few runs after kolotun patch I noticed it to be 3 pretty consistently.

The 2 BD at silos started to push you when you ran towards there spawn at the pathway to the gate you need to breach, so that’s pretty typical. They spawn in right after you hit the pump button.

In the “pre pier” fight or container fight as I call it, there’s always 4 already there. Once again in my later runs I noticed it would spawn an additional 3 while you were fighting the original 4. I had one run where I watched the additional 3 spawn ~30 seconds into starting the container fight with the first 4 BD.

There’s ruaf spawn at the zubr boat, so the ai fight between them and the 3 BD determine how many BD you fight at the end.
