Containment Scarabs not containing

2 out of the last 3 T17 maps run with containment scarabs are still full of normal mobs.

If you're taking Invasive Adversaries atlas passive for difficult monster packs, there is a specific monster/pack that cannot be contained, so it causes all the monsters to spill out plus you still get whatever was contained. You get variance because whatever monster/pack is bugged doesn't always spawn.

Was reported several times since the passive was added, no fix yet.

That must be it, I had that allocated. Removed it now and will see if that fixes it. Thanks!
