A brief playtest shows that the trade route gold increase isn't working, but the increased sea trade route range is. I also have a better text for the ability: "Retains 50% of the Happiness benefits from a Luxury Resource if your last copy of it is traded away. +50% sea trade route range. Increased Trade Route gold during golden ages." As for that Egypt UA mod, what would I do to modmod it to have a maximum percentage increase? Just tack on <Max>#</Max> to the yields?
