Can you upload a save from that game, preferably before discovering Liberalism?The trigger for the first Protestant UHV is bugged.
I aim for this victory in my actual vikings game. Researched Liberalism in 1400 AD and took Printing Press for free, founding Protestantism.
I am absolutely sure no other civ has researched Economics or Constitution (checked per WB).
Could it be a problem that I researched Liberalism before becoming Protestant?
