Ah, that explains what has been causing that crash for me lol

Paradox changed the folder structure for modifiers, while this mod still uses the old "modifiers" folder. As a result, the game will crash when you click on a country with such a modifier as the game attempts to render it.
Update needed!

also seeing this error right now while trying to run down a crash:

list of agitators is unusable by 1870 as opening it will freeze the game for a solid few minutes.

Perhaps making banished agitators vanish into obscurity after 1-2y unless theyre historical or popular enough?

hey there. nice work on the mod. i noticed that the AI is quite loose with the exiling, the list of potential agitators ballooned so high that the game lags hard by the 1860s.
