0007154: Maxed-out animal populations cause lag in dwarf/goblin sites
Approaching dark fortress/dwarven fortresses in adventurer mode causes all non-instant actions (moving/climbing/attacking etc.) taking a lot of time and CPU power. I found this in the 'region_world_sites_and_pops.txt':

4: Oltarumer, "Giltblush", fortress
    Owner: The New Tongs, dwarves
    Parent Civ: The Bejeweled Boat, dwarves

    67185 alpacas
    67185 guineafowls
    67185 blue peafowls
    67185 turkeys

1. Generate a world.
2. Export map/gen info in legends mode.
3. Create an adventurer and visit a fortress/dark fortress (haven't verified this happening in any other site types)
4. Retire and export map/gen info again and compare site populations.

There could be other ways populations get messed up when it comes to traveling locally, but the main problem of certain site animal populations breeding out of control should be fixed now.
