Eh, it's not that convoluted.
Lahmians go, they make a roll, plus bonuses and penalties, and they're successful or fail.
Yellow Fang make a roll, plus bonuses and penalties, and they're successful or fail.
Humble Ones and Prosecutors do the same, and they're successful or fail.
Kislev/Kattarin/Alexandra take some actions, plus bonuses and penalties, and are successful or fail. They succeed at secretly stealing a number of Bohka mercenary contracts and have them signed to the Romanovs instead. Several Dolgan Chaos Cults are rooted out. Kislev City is now completely cleared of all Pantheonic Traditionalists. Anti-Vampiric Work continues as per usual, checking all known sorts of vampiric intrusion signs and behaviors amongst the populace on all levels. Tracking is being performed on strange movements in the Yellow Fang, as they may or may not be preparing something for their masters in the skaven.
^ Actions are not taken to remove the minor irritants that are the Humble Ones or Prosecutors. Actions are not taken to root out the Lahmians who, at the moment, are not yet known to have re-entered the game yet due to the fact that they are hiding themselves behind proxies and proxies.
See how that goes?
It's not the craziest thing, without having to write out everything in Actions and Results, its simplified.
"Did the Yellow Fang succeed in subverting the Humble Ones this turn? Roll, apply penalties/bonuses, its a success. So yes. They did."
Then, then next IRL Turn.
"Did the Yellow Fang maintain subversion? Roll, check, yeah."
And so on.
For the most part, with things like all of Naggaroth, Ulthuan, Bretonnia, Tilea, etc. I don't do that. I just sorta...shift things around as needed for story/narrative purpose reasons. But, on occasion, a roll or two or ten shows up as necessary, such as the Everqueen booting the Druchii out of Ulthuan, that sort of thing.
Individual adventures, like Johanna+Genevieve in Cathay, or Alexandra and the Tomb of Shoika, are multiple heavy rolling sessions....but still don't take overmuch that long, its the writing that takes more of it. Or, in the case of the latter, way less rolling, just one or two, but lots of fun imaginative descriptors to cover the period as the muse and wont strike me.
It's not super consistently consistent, but uh, its sort of how things have worked...ish...for a while. And it's still working, or rather my brain is, so it continues to work.
