(Bug?) Revolt chances

Hi,

I started noticing a potential bug with revolt chances today.

In the past, approximately 33% province morale is needed to prevent revolt. Now, it seems that revolt chances is shown as 0% even if the morale is low and has no troop garrison. For example:

- Province morale = 25%

- Garrison strength = 0.0 (no troop there)

- Chances of an uprising = 0%

Not sure if this is a display bug, a bug with the formula, or unannounced game change
