Thanks for the Real Wagon link Alrenous, reading it now.
Divert a water source to make a mist-producing waterfall in the 1x1 meeting room. The mood benefits from mist stack forever. I tried a similar fortress once, and found that after a few decades of standing in mist left a dwarf incapable of ever being anything but ecstatic, even living off cold plump helmet and sleeping on stone.
I'll check that out. I've never made one (on purpose). I just hate to lose the FPS, but then again, FPS is less of an issue when you're not actively watching it (:
Maybe a failed mood or mandate that caused it?
Edit: Disregard that, I missed the >Several real-time months< part.
Did any dwarves die of old age in there? I hear immigrants have randomized ages so they might have bought the farm in those 66 years.
I think I lost a few immigrants that way. Before I implemented the Bridge of Death to atomsmash them. An artifact wooden earring was eventually created out of my precious wood reserve and some stone. It has a cute picture of a dog travelling, and is called "Womanmerged the Dour Sneer". That apparently satisfied the artifact limit for my fort size.
No mandates since all immigrants are atom-smashed, including nobles.
No way to tell if any died of old age, but at least one of my original 7 is in the 9 survivors of the latest tantrum, possibly because I left him training wrestling.
How do you keep goblins out while letting migrants in?
EDIT: Oh, all the children are offspring.
But how do you have the stone stockpiles take from each other?
I did have an idea for letting in immigrants, not sure what is was, and I don't think it was foolproof enough.
The trick was to set up three stone stockpiles. Two stockpiles can't feed from each other, but three can be set up in a loop.
