Confucianism is a strange religion right now since it doesn't convert provinces well but it can harmonize with other faiths. Right now, most players will convert to Confucianism when forming Qing and in almost no other scenario, but there are cases where a pagan religion nation besides Manchu can conquer Confucian land and choose to convert to Confucianism (through the oddly named decision Convert to Buddhism). To this end, I think in this case "religious_events.20.c" should include harmonizing with the pagan religion group. Here are all the cases where a nation chooses to become Confucian that I think should include harmonizing with their previous faith and don't already:
- "celestial_empire_events.2.a" - option from event that happens when a nation is not Confucian but is the Emperor of China
- "religious_events.20.c" - option from event that happens when a pagan nation takes the "Convert to Buddhism" decision.
