yes... the city governor is horrifyingly bad and keeping your population alive.
A very very long time ago, people were complaining that when you went on production focus, the city governor was still kicking out massive food rather than working some of the production tiles.
So the dev. changed it. Now the governor does not care if your citizens live or die and you are pretty much forced to over compensate for food if any of the following occurs:
a) get into a GA (governor resets to all prod tiles and kills your citizens)
b) chop forest tile being used (see above)
c) barb/enemy AI walks onto a food tile you're using. (governor does not look for another food tile even when there's plenty)
d) you get a new production tile from a border expansion
- There's been times where the governor has removed a worker off of one of my 4f farms to place it on that new horse/plains tile for the production during the AI turn. Brilliant!! more production.. where's the @#$@$ citizen to work it?? died on the way bc we needed that farm!!
e) and so forth...
How you can deal with the above:
a) manage your own citizens.
- if you know you're chopping a forest that is being worked, AND you're at +0 food, then don't work that tile when it's being chopped.
- This also includes locking down tiles to ensure the governor does not move them.
b) ensure you have at least 10 food saved up before going to "+0" food to ensure that when a food tile is interfered with, you have a turn of food hanging around.
c) on top of 'managing your own food' in a) it's a good idea to set yourself to food focus even when you've locked down all of the other workers. This seems to be the only way to convince the governor to not kill your citizens when one of the tiles being worked is interfered with (barbs/enemy AI etc will undo your lock on that tile)
d) yell at 2K/Firaxis until they modify the governor back to the point where it won't try to kill your citizens. (but not at the original way too much food point)
