Summary0000486: Fortress wealth calculation includes undiscovered cavern items, causing large migrant waves
DescriptionAs noted in this thread, http://www.bay12games.com/forum/index.php?topic=52966.15, [^] migrant waves are extremely large and rapid.

It may be that whatever fortress size/wealth calculation is responsible for deciding how many migrants one gets is erroneously using natural caverns.
Steps To ReproduceIn theory, one should embark in any place with underground caverns, and then simply wait for migrants to arrive without generating any new wealth, but I haven't tried it yet.

I would like to preliminarily confirm your suspicion. I just now embarked on a location and left it running without any interference whatsoever. Around midsummer (which is really early anyways...) I received 8 immigrants, bringing my total to 15.

migrants pre-first dwarf caravan are a little odd and makes little sense

We're under the assumption that our embarks are craziness and expansion of our mountainhome. So if we're heading off into gods know where crazy-town of an embark location (which most of us do, because we're all insane) no one should be following behind us without suitable proof there's wealth to be made.

back on topic: I had an embark where my first wave was 5, second was 2, 3rd was 18 brining me to 32 before my first winter was over

Yeah. Or at least the first immigrants should be some especially adventurous types. Unless there's a war between civilizations somewhere nearby and then we get some refugees who has nowhere else to go.

I can confirm this: the size of immigrant waves seems to be linked to the miscalculated fortress wealth (bug 0000010), as shown in status screen.

In embarks where I got 10+ immigrants per wave right from the beginning the fortress Architecture value was larger than it should have been (for example, around 780k).

In an embark where miscalculated fortress wealth didn't occur (total created wealth below 10k) I got a total of 7 immigrants during the entire first year.

Going to assume this was fixed with 0000010 back in 2011.
