Lot of monsters to spawned in the map, but im using Ambush scarab of Containment

I found a bug which caused a lot of monsters to spawn in my map. It should not be possible since i'm using Ambush scarab of Containment, which puts all the native map monsters in the strongboxes. I think most of these monsters were spawned by Invasive Adversaries atlas passive, which causes to spawn 10% more monster packs with difficult mobs.

It's was my 12th map using this scarab and atlas passive combnation. I made some changes and this was second map with this exact setup. It is the first time that i encountered this bug and i have no idea how it happened, all 11 previous maps were fine. I did not manage to get a screenshot with all the mobs, but i got about 100k gold from these monsters and lots of other loot.

I sent the bug report via email to the support and they told me to post it here. Since then i encountered the bug again, three maps after the first bug. There were less monsters outside the boxes (i got 40k gold from them)

I got this exact same bug this evening. My map was filled to the brim with mobs, every single square inch of the map that had empty space had spawned a mob in it, as well as my 40 or so strongboxes from the Scarab of Containment.

I just encountered this in a Ziggurat map.
There was so so many mobs, not a single open space without mobs, + the 41 boxes.

Not complaining, but if this is easily replicated by doing something specific or a map mod combo it can create some problems. Because the amount of mobs is like 10x the most ive ever seen in a map and im a "map juicer".

I was using invasive adversaries atlas passive and scarabs used was 1 of each of the 5 ambush. On a typical rolled Ziggurat map.

I just encountered this in a Ziggurat map too - Invasive Adversaries and 1 of each Ambush Scarab. Had an absurd amount of mobs + all the strongboxes.

Adding to this I also just encountered this on Ziggurat.

Got something like this too just now, on citadel map (t17), one currency deli orb on it, all 5 ambush scarab, also got wildwood at start. All map was in mobs and 37 strongboxes.
