The Great People spam I mentioned above seems to be caused by BUILDING_COURTHOUSE, presumably because there is not "SPECIALIST_JUDGE" great person? It can be verified by loading the save above and moving the courthouse from Carthago and Anantavera[sp?] to some other city using I.G.E. The Intellectual GP will spawn there. I've also fixed a typo ([ICON_ODER] instead of [ICON_ORDER]) in the courthouse name text. The modified files are in the attached archive, along with some minor spelling correction for the conversion processes (i.e. "Growth" or "Creation") text.
Incidentally I've been thinking about starting a new git repository on github, at least so that everything is easier to integrate. I know there used to be one, but it seems to be abandoned. I won't do it immediately since I'd have to make another github account, but do you think it's a good idea?
edit: I'm wrong, the GP is set correctly. Maybe it's a bug with non-vanilla GPs? That's the only thing I can think of, but regardless it's still fine to set the GP rate to 0 and it deals with the problem.
