... the Vanilla values are a joke and you will only fight local Uprisings and Civil Wars ...
copy that file over the old one ...
tested it with my late Rome game and had to increase loyalty gain around 30%
so that the provinces are better playable ...
would need more balancing, but at least now it is better
\steamapps\common\Field of Glory Empires\Data
it is in the file
MODIFIERS.CSV
and the value of that variable has to be changed
$MOD_EFFECT_LOYALTY_BONUS;
Even I only changed the values of my constructed buildings I have done it with a text editor and "replace all" , so other buildings are also effected, but I am sure they would have needed it also

At least now I am able to change to an empire , to see what will happen

but you still NEED ALL THAT BUILDINGS to have a good loyalty value
BUT NOW I love my World Wonder
