It's the code on line 307 and below btw.

From what I saw in the mod files, it doesn't. So I decided to learn how to add support for the huge spawn map and yeah, I think I got it! I've uploaded the new Leader_Config.sql on github. I've just converted the .xml script on the relevant file of Australia DLC to .sql script and used the starting location of the Georgians, since that's what Wikipedia told me Ancient Colchia was located.

Hey mate, nice mod
Dunno if it's possible, but does this civ have a spawn point on the True Earth With Historical Spawn map?
