Attention CA: Trade Disruption Bug!!?

This is a great thread, thanks for doing so much research Soulflame & Quietus

Nothing like trashing ones own theories eh? Apparently, I was wrong (again).
I upgraded my port in Halicarnassus into a Shipwright. It used to trade with Athene for textile only, giving me about 600 income a turn.
When I upgraded it, I went trading with another town (Larissa) for Olive oil. But the original Athene route is now not giving money anymore (and blinking). So it is not based on resources, since these are different resources, and it were the only resources that the ciy exported.

So although once again the totals add up like I described before, I again have no facts about why some trade is blinking and not giving money.
The only thing I can now think of is that a town needs a certain population to manage another trade route, and it uses labour from the lowest income giving up. This would mean that once a town is grown, the blinking should stop (unless the demand for the product rises with the same amount). This would explain why upgrading a port sometimes give blinking trade immediately, and lower incomes (since the lower gets preferred, and there is not enough labour, you'll loose some income) But I can't really test this, and it seems a bit silly to me.

Other then that, I have no idea what it could be. I'm going to continue with my campaign, and maybe later in the game (when I have more towns) try to figure it out with some more experiments.

@soulflame - read most of your posts, didn't have time to read each of them in-depth. I ran similiar tests, and at first it looked like enemy fleets and armies (enemies to my trading partners that is) that were in potentially threatening positions might be the cause of the blinkers.

However, I found one internal city, no overseas trade, all sea trade was with my own cities, yet it had the blinks. Dispersed my nearby fleets and troops, just to make sure A) no possible enemy/rebel nearby and B) it wasn't the "fog of war" along sea routes that caused blinking. Nope, clear as could be. Since the blinking was between CityA and CityB, i checked CityB - no blinks. No sense, how could CityA's sea route be threatened, but CityB's route is fine? Then, someone over at .com said it looked like cities with Shipwrights and above always get the blinks. So, I checked out every single city and sure enough, that was the case. Shipwright and above - always blinking, Ports are always fine. Total trade income in these cases was always the full (blinked) amount every turn.

But, sometimes, blinking is correct - if you just attacked a faction you trade with (or they attacked you), that turn you'll see blinking but in this case, it's for real

edit: forgot to mention, when i was running my tests I was only at war with the Gauls who had no navy, so there wasn't a single boat in the Med that was a direct threat to me, except for the rare rebel ship I've seen once.
