It looks like the Faction Wars is still working but in broken up stages.
You have to keep going back and forth between the levels to jumpstart
the action and I still have not flooded the Agroprom Underground yet.
Too early for me to really pass judgement yet other than I have only
found a single Dutyer with an RP-74 whereas before I would see 3 or 4.
Acording to my observations in this game, Duty settles down in Garbge once they establish control over some specific points (the camp between the East pile and Flea market seems to be one and the "Camp in through" the other - when they lose these they'll recapture them or move troops there - but they won't move out from there even with 2 squads present). With these points settled, Duty won't take the initiative to move out Agroprom or advance in Garbage unless their faction strength is nearing 300. When that happens, they do send a few squads towards Garbage; i'm guessing there might be the bigger objective to establish a safe route between the Southern Entrance to Dark Valley and Agroprom-Garbage Northern gate; however, since by then the Bandits have regained some strength and often re-captured the points Duty took over in their mini-exodus (Barricades, the point between South Piles and Barricades; occasionally Diggers' camp), Duty will spend all the strength surplus on re-re-capturing those and has to gather strength before they attempt anything again, during which the Bandits will also reinforce their position.
So basically it's a cycle that repeats with some variations.
(Again, what i describe here is based on ingame observations only - people with the script insight could probably explain it through more specific parameters.)

Duty suffers from a bug which prevents squads which spawn at their base from moving out while the actor is on a different level. Also, Duty doesn't advance in the factions war further than the two Agroprom entrances to Garbage, because of the precondition actor_in_faction, which is false unless you join, which then evaluates to true. The only reason they move further is that they have a secondary target at the barrier - this is what pulls them into the Garbage and beyond.
