Incite Revolt Agent Function Nerfed for Epirus?

[Hieronymos]

Am playing DEI 1.04a Epirus on H-diff. Turn 99--have taken all of Hellas + Italia + Cisalpina + Brundisium.
Brundisium currently has Greek culture of 56%, and morale of 100(+23)

Have trade + n-aggress treaties with Carthage; but wanted to take Cosentia & Syracuse off their hands by using old tried and true method of inciting revolts.
Am using 3 lvl. 9-10 spies (two taken from Sparta & Athens at game start), over 17 consecutive turns. With skill lvl at 90-95% they have mission success almost every turn.

Even when successful incite revolt action has Cosentia or Syracuse morale at "-97(-21)" or other negative numbers, there is never a revolt, as next turn morale is magically back at "-80(20)".

Neither of these settlements have temples or other morale-increasing structures, or occupying garrison armies (a 10-unit fleet did just arrive at Syracuse).

Question? Is the incite revolt function somehow disabled in DEI 1.04a? Or is there a special DEI methodology for revolt incitement? Or are there pro-Carthaginian or anti-Greek buffs/debuffs I'm not aware of?
Or is this just some vanilla patch dynamic I'm goofing on?

Any advice most appreciated.

If PO is at -80(+20) it means there is a revolt in progress...

Essentially you will always get +20 PO if the revolting army is filling up/recruiting to simulate the fact that dissidents are leaving for revolt.

Sounds like they are just stamping out the revolt early in the process before it really gets going which takes 3 or 4 turns. Turns 1 and 2 of a revolt it's easy to crush the small force that assembles.

It's working just fine.

When you have a rebellion/revolt in a province. The public order goes from -100 down to -80 because every turn those revolting troops are recruiting more units, you get +20 public order.

If the forces are attacked but not defeated and move, then you start getting more negative public order.

It's something that's been in Rome II since launch.

Reloaded an earlier save, and moved one of the spies to Lilybaeum--where the revolts were actually happening, and where there was a garrison army to stamp them out.
Bummer...
............

edit:
It's the increased DEI garrison size that makes spy-induced revolts ineffective.
If only 4 rebel units initially spawn, they must last quite a few turns alive to be able to overcome a 15 unit DEI garrison (except Carthage's, as they're pretty weak).

The slave revolts in the now defunct Toon mod were the other extreme, and OP: a full stack of 75% professional troops, all with 4 exp chevons.
