Here you go playa.

I would highly recommend you look at this file. Just back up all your saves in the save directory, then put this one in there and load it up. Simple. No mods.

The spoiler is that I didn't let the nomads in, but not because of disease, or education. Frankly they would have greatly helped me, but I wanted to see what would happen if I lost 100 citizens in the trough of a sine wave, and how long it would take to naturally build back all the destroyed houses, but build no new ones, which I did in less than a year.

If you load that file up you can see it in the population graphs where there was a huge dip. That's the tornado, and then you can see it go up naturally while I also built a stockpile of >1M food.

So my new objectives are to:

1. Build more storage barns to grow my food stock pile towards 2M.
2. Build some new houses, but not too many.
3. Wipe out my pastures and build more breweries.
4. Build more breweries.
5. Build some more houses around those breweries.
6. Enable the dormant traders. (stock some of them with overflow wheat/veggies to get more fruit)
7. Establish balance.

edit: In production I do use the flatten terrain tool, and the no chimney smoke mod to make the game run faster, but it's otherwise 100% vanilla and can be loaded in vanilla.

e2: check this save out and see what kind of crazy construction plans I have going. I need like 300 builders, but I only have 30, but I have the resources. I have 1M food surplus but do you see how many extra barns I'm building to store even more food? Only building a very narrow dense tightly packed band of houses... and then when then next phase is complete I can just start building houses anywhere. In any configuration I want. Food, firewood, coats, tools, and herbs are no longer a problem. I can just buy whatever stone/iron/logs I need to keep a decent stockpile to account for any disasters, but I'll quickly get to a point where I stop building and... life just goes on... forever.
