After all the discussion about governments and corruption, I decided to add the City Improvements Forum, Court and Parliament, which all are tagged to reduce corruption. Added also the GW's Angkor Wat and Taj Mahal which had the wonder flag to reduce corruption. But playing, I found some examples where putting a Forum AND Court in a city had the same corruption as only a Forum. I assume in this case that the corruption isn't changed because the percentage threshold hasn't been reached. Anyone know what the percentage is that's affected by any modded Imp that reduces corruption? Also, very annoyingly, I found that Magellan's Voyage (Circumnavigation) gives a +1 to ship movement, but if I already have the Great Lighthouse, my ships don't get a +2. Seafaring +1, GLH +1 =+2, but Seafaring+GLH+Magelan's = +2 also. Can this be avoided?
