Countries switched to protestants in the instant

[WolfWarrior]

So i played a game where the moment protestant reformation started whole Bohemia and Poland switched to Protestant. Now this could be ok by their whole countries were already converted. Like in a blink of the eye. And protestant reformation started in England. Is this some kind of event or something ?

I think Hussite countries have the option of instantly converting all Hussite provinces to Protestant.

They most likely were Hussite. When Bohemia converts to Hussite and completes their mission, the newly created center usually targets Polish provinces and Poland eventually converts too. When the Protestant Reformation starts, most Hussite tags convert immediately due to event. The event causes all their Hussite provinces to be instantly converted. It’s a pain if you are playing Hussite and your vassals and other tags convert to Protestant.

Sounds like we need an flag rather like CK2/3's for preventing the Norse culture split or I:R's to "Secure the Antigonid Position," where if you can get the Hussite faith doing well enough you can prevent the event from firing globally.
