bug in food production??

[Long Happy Man]

I'm in the modern age and have many 20+ size cities. Since having extra citizens are useless as specialist, I decided to starve some citizens to limit the city sizes to 20.....just enough to work on all tiles.

I zoom into of the cities and noticed it was producing 2 extra food, so I instantly sent workers to convert a farm into a mine. I was surprised to see a shortage of 5 food after that. Then I convert it back to a farm and now there's a shortage of 1 food. huh??? anybody experience this before?

Perhaps you have some other tile polluted. Polluted tile produce nothing but waste.

[Long Happy Man]

no there was no pollution. I was sure nothing else has changed, I did all the changing within one turn. Oh btw on the next turn it shows 2 surplus food again, I tried the same thing again (change to mine) and it shows -5 food again.

Have you tried manually checking how much each worked square is producing and comparing that to the total?

[Long Happy Man]

yeah I did. it was a grassland land so it was producing 4 food (2 from base production, 1 from farm and 1 from railroad). If I changed it into a mine shouldn't it produce only 2 food since the farm and bonus from railroad is removed?

There is a bug in food production, I reported it a while ago. When you have a 20+ size city (or all tile being worked), a one tile gets pollution, the worker becomes a specalist... but you still get the FOOD from the tile (that is polluted), if you clean the pollution then you get two time normal food production from that tile when you put a worker on it! (It might be the same for shields and trade, but I never checked). The problem comes when you either build/destroy/change any of the tile improvements in the city influence OR the city grows. At that time the city correctly recalculates the correct food production, often leaving you very short (since it usually happens after city growth). It's a very annoying bug, and makes it hard to stay in WLTKD as your cityies tend to go through cycles of "bonus" food and starvation.

Hope this helps.

Yes, I've noticed this as well. It's quite a pain, because you have to check your cities continually to make sure that they're producing the right amount of food. I should point out, though, that I've only ever seen it on tiles where railroads enhance food production. Forests and Hills don't seem to produce the problem. Additionally, you can work around the problem by forcing the program to recalculate the food in the city radius. Unfortunately, you cannot accomplish this by reallocating workers to different squares. If I notice this happening, I usually send one of my city's offensive units out to pillage a tile with railroad, which forces a recalculation, then repair the railroad immediately with the workers that are already there to clean up the pollution. This avoids the buildup/starve-down, but it's quite an annoyance regardless.

good idea

I'll give it a try

It affects food, production, AND commerce.

Here I posted a screenshot of a city that had polluted on its mountain tiles several times. Look at the production.
