Scanning through schema files, I found many tags that have been never used. So I tried using some of them for trait. Code: <GreatPeopleUnitClass> <iGreatPeopleRateChange> I think I set them correctly and they were shown in the pedia. (attached image 1) But they didn't do anything. (attached image 2) @TB I assumed that they were added by you. Could you look into it if you have free time?
