Great Scout was gifted to me by CS and I was exploring map, found nice spot and wanted to found a colony (using CiD too), he had Colonial Settler promotion and I was able to click "found city" button, but I wanted better spot, so I explore little more. Then, barbarians attacked me and my Great Scout lost ability to found colony, but he still has that promotion, I mean I can't see the button. I thought that if he's injured he can't settle. So I run away, healed him and tried again, but still no button.
So, what requirements are needed for Great Scout to settle? Or is it a bug? There are no any cities 4 tiles away (even more).
Edit: I copied him via Terracotta Army and he was able to settle (that clone). I embarked and traveled him to the island. Still could settle, but changed my mind and embarked again. When I reached other lands, button to found a city was gone
And second question - how to lvl up Scout? They are on 3 lvl and 47 XP and don't get any XP - neither from revealing tiles nor from battles.
Edit 2: I am using CP + CBP + EUI (full pack) and yes, I enabled CBP support in settings file. Do you need any logs?
Edit 3: I read previous posts and noticed that XP cap is coded in Community Balance Patch > Balance Changes > CoreDefines.sql, I changed it to 210 (I think it's 6 lvl) - do I need to start a new game to apply changes?
