So I had decided to kill off all of a world's civilizations in adventure mode. It was going pretty well, I had almost killed off all the humans and went to visit the world's dwarf fortress. After killing several dwarves in the entrance I descended to the forge area where I could hear a large group of people. I went to explore the other direction, which caused a new area to load. However, when I returned to the area with the large group the game suddenly slowed to a crawl, with it taking 20 seconds or more for me to move a single tile. I retired when I went to look at the world's new population, I noticed something odd. Each tame animal in the dwarven fortress had a population of 374. After that, any attempt to visit the fortress would result in the game crashing, probably because of this:
3: R¨thar•nul, "Trammelmirrored", fortress
Owner: The Lone Rock, dwarves
Parent Civ: The Savage Trumpets, dwarves
67 dwarves
215892 dogs
215892 cats
215892 mules
215892 donkeys
215892 horses
215892 cows
215892 pigs
215892 chickens
215892 cavies
215892 ducks
215892 geese
215892 llamas
215892 alpacas
215892 guineafowls
215892 blue peafowls
215892 turkeys
215892 rabbits
4 dwarf outcasts
As you can see, a bug is causing the tame animal populations to increase wildly. Animal populations in other sites are normal. I see that the changelog for 40.04 lists a bug fix for civilized animal populations, but obviously the issue hasn't been entirely dealt with. This world was generated fresh in the latest version.
A quick test with another new world yielded the same bug in another dwarven fortress, at least insofar as the animal populations were all the same. I did not test to see if they increased.
If this hasn't been reported (or re-reported) already I'd appreciate it if someone more familiar with the bugtracker would do that for me.
Here is the save:
