[0.291] Economic oddities

Playing against 2 opponents, I managed to get a conquest victory by defeating the other 2 sovereigns and the grown daughter of one of them.  Along the way, though, I noticed some strangeness with my income and expenses.  I had a steady income of about 20 gold per turn just before attacking the first opponent.  I had 3 towns, each of which had a tax office and a couple of markets.  After capturing my opponent's towns, my expenses went through the roof.  Towards the end I was losing over 40,000 gold a turn.  Needless to say, all my units deserted, and I ended up with negative hundreds of thousands of gold.  Is that normal?
