I have 4 towns under my control and my tax income is 0. is this a bug? Doesn't seem right.
that's weird... but don't you have all your population used as soldiers? (the population icons - figures - are empty)
Yes, elvain may be right. :) That's why when I go to war(with a small country), I set the tax income to zero. I don't get gold anyway, and there is a -5 rebellion risk bonus. :)
