0006804: Human overpopulation
Arguably erroneous populations of humans and dwarfs in small worlds. Creatures are tightly packed in buildings, one on top of each other. Excessive and obstructive amount of dialogs is handled, in addition to pathfinding and other movementh checks, drops performance (not to mention the immersion).
Standard wordgen parameters, but small world size. 1 of 5 generated worlds on my pc represents this problem in one way or another.
First world, elves couldn't make it through worldgen (250y). Dwarf quantum packing example:

I highly recommend to visit any human hamlet to understand the bug better.

On the 4-th worldgen I've got a less severe example:

I have encountered the same thing, I found a 3x3 hill dwarf mound with approx. 150 dwarfs in two piles.

This is specially evident in dwarven hillocks.
2014-07-10 04:36   
Yeah, hillocks don't seem to expand as their population grows. I haven't seen the hamlet problem, might be an unrelated issue.
2014-07-10 08:24   
Well, in the attached save hamlets are overcrowded too. Laggs like in the DF2012 towns.

There seems to be massive overpopulation in some sites.
In my current world there is this site:

560: Epxamete, "Shankweb", hamlet
    Owner: The Tin Fellowship, humans
    Parent Civ: The Abyssal Kingdoms, humans
    lady: Thinir Glidedteaches, human
    12759972 humans
    <a few animals here>

While in the whole world:

Civilized World Population
    204893 Dwarves
    13044072 Humans
    73371 Elves
    244149 Goblins
    3780 Kobolds

So 98% of the human population of a Medium world lives in this hamlet...
Someone on the forum even reported a site with 34 million humans.
There is certainly some bug there, some variable is going very wrong.

I wonder how this manages to coexist with 0005432. (Is there a "has antithesis" relationship?)
2014-07-13 23:42   
Hamlets don't have temples or sewers, so, I guess, there is no relationship.
2014-07-14 05:23   
I had the bug with worldgen generating millions of humans.

I fixed a problem similar to but not the same as the animal population problem that caused this to get out of control. On the other hand, there could still be some more slight packing due to small population expansions that'll need to be handled differently when towns actually expand properly. But if anybody sees millions of people living in a hamlet in 0.40.04+, this should be reopened.
