Trade Route Disrupted

[photophor]

I've seen a 'trade route disrupted' warning a couple of times. I don't recollect seeing anything that might take me to the problem hex but that might be my confusion because its a new game and a lot of stuff was happening.

I did look at the Strategic View (F10) and set it to 'Trade Routes' overlay and 'None' Icon Mode.

I'm guessing the yellow highlight indicates an active trade route although I can't see anything in the manual to confirm this. If that's so, I do have some breaks.

Each of my cities is connected by a road. There are no units on the road; hostile or friendly.

So why are my trade routes broken?

Is it possible that one of the road tiles got pillaged? That can be hard to notice graphically.

Good idea! I went back and checked. Every single hex shown with a road in my screen shot did, in fact, have an intact road.

I also took the opportunity to see if there was any financial information that might help - screen shot attached. This isn't all that helpful as all the ocean side cities had harbors.

And that's really odd because both Singapore and Kyoto have harbors but only Kyoto is highlighted in yellow.

So the strategic view appears to be saying that Singapore has no trade routes by sea or land and the financial screen is saying that Singapore is making 15.01 gold per turn from trade routes.

I have the same problem where routes will say they are broken, but the next turn it says they are connected. I assume it is a bug?

I think it might be from barbs crossing the trade route and then moving on. I saw this by sea, where the route was blocked because a barb ship passed through. I'm not sure if you actually lose a turn of income, though.

I get trade routes disrupted and connected randomly as well. I've no clue what the story is. Roads and such are all in tact. No war or much else that might complicate matters that I can think of.

I'm glad to hear other folks have noticed it too.

I have seen the same thing. I am wondering if it is related to the fact that I had trade routes associated with critical resources that I had fully utilized?

Did you check for blockades?

Welcome to CFC forum!

Nope, roads don't care about resources at all, and roads are not associated with resource. You don't have to build roads to connect resources, only to connect cities for trade routes.

Good idea! I hadn't.

The attached screen shot shows the same area with unit icons all of which are mine so I can't see anything on land or sea that might be blockading. Also, I'm playing this first game at Settler level and at the time I'm illustrating in this forum I'd got complete control of the whole continent; all city states were allies.

My suspicion is that this has something to do with having a city connected both via harbor and road. I didn't start having this problem until I started building harbors. I am the sole occupant of a small continent with all my cities connected via road and they have been for millenia. I start building harbors and suddenly my trade routes get disrupted? I haven't seen a barbarian on my continent in millenia either, but there are a couple tiles that are fogged on occasion (very few though, so why I haven't seen a barb in ages).

After some more digging I think you are right. In my case the inland cities are shown as having a trade route connection to the nearest seaport. The seaports do not use the roads to connect to the capital and appear to be connected to the capital by sea. The screen that shows trade routes only shows the land routes.

I'm still not sure why the seaport capital of Kyoto has an unconnected yellow trade route marker but the seaport city of Singapore has none.

I agree. In both games I have played I didn't see unexplained and inexplicable trade route disruption messages until I started building harbors.
