Actually, found a fix!

You need to go into the mod file (usually in your user's Documents/My Games/Sid Meier's Civilization 5\MODS/JFD's Civilizations - Brittany (Nominoe) (v 2)/Core) then open the file "BrittanyNominoe_GameDefines" with a text editor (noteblock, etc.)

Then look for the LEADERS section and the VALUES line. There should be a "ArtDefineTag" whose value is for the Burgundy mod for some reason. Change it to 'JFD_BrittanyNominoe_Scene.xml'.

Worked for you, should work for you.

Adding a little update here : there's still a gray background when talking to the civ leader.

No clue how you could fix this, so I'll leave this here.

I have the same issue with a gray background and scene could not be found

Been using this mod for a very long time just yesterday while playing and meeting the Civ in game got a gray background with a message "scene could not be found..." Re-downloaded it a couple of times and still didn't work.

Wonder why it would happen all of a sudden

THANK YOU

Not sure if there are compatibility issues (I do have quite a few mods) but I get a CTD as soon as I end the first turn after founding a city.

I played another one of your civs before this (Laos) so not sure why this would be quite different (well, except for units, tech, etc.).

I tried about four times with the same results, i.e. CTD, so I think I'm going to move on for now.

Thanks.

How about a mod that let you choose the UC.

oh Ive been waiting for a mod like this for ages, awesome
