Okay, in my Byzantine Playthrough, I own everthing from Khwarezm to Egypt to Dacia to Mauretania. Basically, a pretty big empire. Generating an insane income to say the least. In fact, I generate so much money that I think the game can't handle it. I currently have an income of 103 531 620. Yes, 103,5 million per turn (minus 109 374 in expenses, but still).

Now normally, I would be fine with this, but the game tells me Im on the verge of bankruptcy next turn. This happened to me once before, around turns 100-120. I suddenly ran out of money and ended up on a minus 50 000 income. It gradually bounced back and now it seems like it will happen again.

Has this happened to anyone else? Does the game actually have an income limit?
