Holier-than-Thou Settlements: Bug or Feature?

According to the game manual, people in a settlement like a pious governor. I was playing another campaign as Spain when I noticed that my settlements with governors were all suffering from low public order. Each point of piety the governor had was adding 5% religious unrest to the settlement. Moving the governors out dropped the public order back to normal.

The governors did not have any bad traits giving unrest. The settlements were 100% Catholic. I've noticed that when the settlement is 99% Catholic or lower, this religious unrest does not occur. So, is this a bug that occurs when the settlement hits 100% Catholic, or is it a feature, some sort of 'holier-than-thou' citizenry that looks down their collective nose at the governor's display of piety? Is this a 'divide-by-zero-oversight"?

Interned or unintended the whole issue with families and traits need serious work. I thought that RTW was hard on governors. I used to hate sending diplomats all over the world in MTW to remove titles from corrupt governors and more than half the time just disbanded the units.

In this game there is nothing that won't cause bad traits to apear....

I am sorry but I am a bit fed up with have to fight battles or insure the survival of a line which are totally worthless. No part of it makes any sense from selecting heirs to governing cities. At least in RTW you had the 50,000 threshold before you had to worry too much with the tax thing. If they are supposed to be trusted governors then why make it imposable to use them.

I am sure it was unintended but it is still stupid and a major disappointment.

I doubt very much that this is a feature, I'm fairly sure your right with the 'Divide By Zero' theory, either that or something similar.

I'll test this when I get the chance, and see if I get the same thing.

@ Fisherking - I agree with pretty much all of your post, but that's another story.
