Ever wonder why the A.I. just.. stops.. colonizing in about the mid-16th century? It's because they don't have any colonists! I loaded up as every major power in my game, and they all had max innovation. This also means that they don't have any missionaries either. I highly doubt this is solely because of events, the A.I. is actually moving the sliders; I noticed that most of them couldn't change policy for several years.
Unfortunately the mysterious A.I. is hardcoded, but maybe a band-aid solution would be to make missionaries/colonists right-specific on that slider.
