Is this on top of the Judiciary Court's +1 per Era effect? If so, that's going to nearly double the number of Magistrates earned, which may end up taking a lot of the Decision-making out of Decisions. Also, I'd still like to have Promote the Arts and Enlist the Services of a Great Person (forgot the exact name) have a chance to spawn UU GPs, just at a much lower chance. 5% sounds reasonable. It's not unprecedented, considering that Civs can gain UU GPs from the Patronage finisher without a single mod active. Now, I don't want to just complain, so I want to say: excellent work on this mod! I'm about halfway towards getting support patched in for all 25 of my Civs and it's allowed me to open up a whole realm of possibilities for them.
