Hi,
I suggest to check this topic, very helpful:

Some changes were made in the patch in the leaders and the civs, the most common issues are:
1) In modbuddy click on your graphics file , go to properties and set the "Import into VFS" to "True". This is required to enable your files.
2) Changes in the leader files:
<DenounceWillingness>7</DenounceWillingness>
<DoFWillingness>4</DoFWillingness>
<Loyalty>4</Loyalty>
<Neediness>4</Neediness>
<Forgiveness>5</Forgiveness>
<Chattiness>7</Chattiness>
<Meanness>7</Meanness>
<Row>
<LeaderType>LEADER_ALEXANDER</LeaderType>
<FlavorType>FLAVOR_NUKE</FlavorType>
<Flavor>7</Flavor>
</Row>
3) In case there are duplications there will be issue with the mod, for example I had these lines twice in my mod and it didn’t work:
<Row Tag="TXT_KEY_CITY_NAME_HUNCENT1">
<Text>Buda</Text>
</Row>
