0004025: Kobolds still starving to death early in world gen
Looking over Legends mode, I'm seeing many cases such as this: http://i.imgur.com/LGusr.png [^]

It doesn't matter if the kobold was born year 0 or year 3, they all die in year 4, all of starvation. Looking over Legends it appears that some dwarves and elves suffer from this as well, but as it stands right now not a single kobold makes it to the end of world gen.

I can confirm. Year varies but it always under 5.
2011-02-24 10:34   
Whole bunch of dead kobolds at about year 4, yeah.

I'm listening to the DFT now, and Toady mentioned earlier that goblins don't actually eat food. I'm guessing that it's just an oversight where golbins and kobolds and all them don't produce food, but kobolds still eat it, therefore starving to death in short order.

Just checked legends; it says the cause of death is starving, so I'd say that's what's happening. Eating but not making food.
2011-03-01 06:11   
I can confirm this, but also add that I've seen a number of worlds that most of the pop starved to death. Most notably was the elves that tended to live for a long time but then suddenly died around the year that the world gen stopped.

Getting something similar with megabeasts. They all seem to starve if they take over a civ. World entered the age of heroes real fast.

Goblins had [NO_EAT] added as of 0.31.19 to their entity in creature_standard.txt hence they're not being affected (there are some beasts also with the tag like magma men, iron men etc).

As far as food generation goes, in entity_default.txt the Skulking (Kobold) & Forest (Elf) civilizations only have [PERMITTED_JOB:HERBALIST]. Humans & Dwarves also have [PERMITTED_JOB:PLANTER]. Humans, Dwarves & Goblins also have[PERMITTED_JOB:BUTCHER]

I think Elves may be surviving for longer as the forests they set up in have more plant life to allow plant gathering to generate enough food to sustain their populations where as Kobolds live in caves where it's not viable to live off foraging alone.

Until creatures/civilizations get some way to acquire food through non-production means (theft, trade etc) I would try adding [PERMITTED_JOB:BUTCHER] and/or [PERMITTED_JOB:PLANTER] to the Skulking civilization in entity_default.txt & see if they survive longer (or go for the easy way out & add [NO_EAT] to them in creature_standard.txt) & vice-versa for the Forest civilization.

(.31.21) All kobolds are gone from the map in a matter of years, while goblins and humans (usually in the same civ) are practically everywhere except islands. Tried at least half a dozen worldgens, wondering if they just got unlucky with a bronze colossus or something, but they just keep dying out.
2011-04-09 05:33   
Most dwarfs seem to be dead by year 10 in world gen due to starvation.

I guess this may be because mountain biomes do not allow planting...

(edited on: 2011-04-26 17:49)
The other civs make it through world gen just fine (although I only gen to about 250 years, so I may just not be running it long enough,) but I haven't had kobolds in a while. I'd been assuming one of the Civ Forge races wiped them out...

2011-06-09 18:13   
Possibly fixed in next version (may or may not be 31.26) - per Dev Notes on 06/09/2011:
"I also put in some extra precautions and tweaks so that dwarves form markets properly and are more survivable in world gen. Kobolds as well."
2012-02-15 21:39   
I don't think this was fixed, per se. It looks more that the "protection" kobolds and co. receive is that the starvation counter begins at year 20 instead of year 0. Perhaps this is meant to give kobolds long enough time to establish food stores, but I'm still finding that entire kobold sites die anywhere from years 24-27
2012-02-15 23:26   
Looking at legends, all historical kobolds appear to die from starvation about 3 years after they become historical.
2012-02-15 23:46   
After 250 years of history, my adventurer has repeatedly been accosted by kobolds. It seems this bug is no longer present in the new version.
2012-02-16 07:01   
Reminder sent to: Kumquat, SirPenguin

Since it appears that this no longer happens in every world, it might help if you provided seeds for worlds where kobolds died out early.
2012-02-28 19:35   
So, definitely fixed now because he removed starvation

Historical figures does not include entity populations, so this may still be an issue.
2012-03-07 17:57   
I think the particular changes in 34.03 pretty much resolved the intent of this bug report without reading more into it.

If anyone is finding their populations depleting (not historical figures in legends) because of what seems like unnecessary starvation from famine, please open a new issue, or if you feel you have something to add to this report, please PM a manager on the forums.
