Hmmm, I should have cut that while band...
Look at the incomes : 28d and 30d. Base taxes are identical, pops are in the same range, goods are identical, no manus, TC+CJ+gov everywhere.
Yet, production taxes and tolls are different.
Guadeloupe and Barbados have 11.7d production and 8.8d tolls, while Martinique and Tobago & Trinidad have 10.8d production and 8.0d tolls.
I first said myself, when I saw the difference (by chance, because once colonies are finished I don't look at them in details anymore), that populations where not the same. But they're in less than 100 inhabitants separated. Moreover, the two most populated provinces are... the poorer Martinique and T&T.
Guys, do you have an idea, or did I stumble on another bug ?
