ok pevergreen, i think i've found a bug-since the last patch (i think-i haven't played for a week), none of my cities have been giving any tax income. This happened with both portugal and the marathas, and on both a saved and a new game. Obviously this is a bit of a nuisance. Trade and other income is normal, the cities aren't tax exempt, tax levels are normal etc. Also, this isn't occuring on the vanilla version.
If anybody could give any advice as to how to fix this, it would be much appreciated.
