Just to dive into some of the changes more without cluttering the change notes.

I don't know if it was luck, the new plagues, or what, but I felt like the catholic church was off to an extremely bad start this game so I decided to make several very minor adjustments to fervor. When a heresy happens, the main religion got 4 fervor per defector, and that is now 4.5. Virtuous priest exaltation was 4 and is now also 4.5. The heretical religion used to get 100 fervor to prevent flip flopping, but I changed that to 30 as it seems more than enough.

Making a holy order is reverted to 10 fervor (I had previously set it to 15). Instead, getting your holy order expelled is buffed to 15. I think basically the losing side of an ongoing holy struggle should have high fervor. The winning side should be struggling with heresy as everybody is tired of "holy" wars.

I played a long game with black plague set to unlimited, but default rarity. Felt like every 15-50 years there was another black plague. The world really never recovered. Most of the map was constantly low on control and development. Besides my capitol with 100 plague resistance. So I felt it necessary to both scale back the chance for black plague to occur specifically (not other plagues), and adjust back some of the travel speed and safety I took away when the world was much safer before this patch. I had found myself unwilling to attend events because of the danger, and that's probably not great gameplay.

I had originally made all the health maluses more dangerous because prior to plagues the world population just grew to insane amounts and I was trying to reign that in. But now the population control seems to be working just fine. Diseases have default negative health, but retain the additional negative prowess. I changed wounded to be closer to default, but moved the additional penalty to botched treatments. This way fewer flagellants will end up killing themselves. Severe wounds or higher are still a major problem, and wounds that get botched treatments are a major problem, but minor wounds that receive adequate treatment will once again be trivial for otherwise healthy people
