Excuse that I come back to this theme again, BUT. To a patch 1.1 help showed that (for example) from one farm at me just 5 foods. After patch 1.1 help is shown that from one farm arrival to a season +5 foods.
Besides at technology research (which increases food arrival by 25 %) there is an addition of 1 food in a pool, and the help writes that arrival of food to a season +1.3 (for example). We look further. In the future it is possible to build houses giving +100 to the population which demand (from resources) -1 food per turn! But if the gain of food isn't present, these houses what for are necessary???
Therefore I also have brought up a question: whether a bug it.
PS: sorry for bad english
