Summary0006220: Depopulation of underground animals when playing Adventure mode
DescriptionAfter playing an adventurer for a short in-game time, numbers of underground wildlife drop sharply. In a pocket world all underground creatures are extinct after a few in-game days. This affects cavern and magma creatures and vermin. Demons, forgotten beasts and (as it seems) underground civilisations are not affected.
Steps To ReproduceCheck population info in a world, play an adventurer for a while, check population again.
Additional InformationFirst noticed in 34.07, the issue occurs still in 34.11.

Quietust suggested that the game spawns creatures when travelling over an area and then forgets to add them back to the population.
TagsNo tags attached.

According to the latest dev log, this seems to be fixed for the next version.

05/06/2013: "... I also fixed a bug that caused the wilderness populations of underground areas and rivers to slowly vanish and die when the area is realized tile-wise repeatedly, and some other such problems that popped up playing with the world debugger. ..."

Not fixed in 0.40.01.

Tried one world so far, will test some more, but it appears underground wildlife numbers still decline rapidly after adventuring.

 After XXSockXX I tested, an confirm its not fixed.

I saved the world_sites_and_pops after creating a pocket world and played a bit. I didn't even get to reach any underground parts, and after one day in-game (plus the 20 automatic days of the calendar) I retired and accessed legends mode, where I exported another world_sites_and_pops...below there is a comparation between them
  
First Export:
      872 gorlaks
    867 trolls
    578 giant cave spiders
    161 giant earthworms
    503 gremlins
    4037 troglodytes
    347 giant moles
    322 giant rats
    206 large rats
    1409 dralthas
    2255 pond grabbers
    580 giant toads
    590 giant olms

Second Export:
        126 gorlaks
    121 trolls
    57 giant cave spiders
    49 giant earthworms
    102 gremlins
    348 troglodytes
    72 giant moles
    45 giant rats
    30 large rats
    224 dralthas
    154 pond grabbers
    59 giant toads
    69 giant olms

Maybe Toady commited an oversight when he was fixing and it is easier now. Probable Quick fix?

 I tested it in 2 worlds, results are here:

I saw Toady mention that he didn't fix old bugs for the big release, so maybe this will be taken care of in the next fix release.

EDIT:
Did a quick test, it's still in 40.02.

 For the record, it's still in 40.03, it's probably just not high priority right now.

I'm not sure if it's related to 0007216, I noticed it first in 34.07 adventures where I played for a long time, but I never encountered underground creatures on the surface like what's described in 0007216 (except for the leather issue in lairs).

 Still happening in 40.11, and I think they're locally extinct now where I've been travelling around.

Initial legends export after worldgen:

Giant Cave Spiders: 115211
Giant Earthworms: 105697
Blind Cave Bears: 102014
Cave Dragons: 57915
Green Devourers: 48564
Gremlins: 29783

Legends export after copying and retiring the copy on the 16th of Felsite, so, this is three months later:

Giant Cave Spiders: 103044
Giant Earthworms: 98424
Blind Cave Bears: 81189
Cave Dragons: 51855
Green Devourers: 44019
Gremlins: 24958

Though it is slightly tangential, population crashing upon adventurer visiting also occured by a large margin in @LordKnows note (issue note link beneath) in issue report 0007526 where trying to enter the city of 'Pointrose' which was massively overpopulated with flymen and laggy 2 in game weeks later caused masses of them to suddenly die & stablise at as smaller amount.

Wheras the other test site that wasn't visted "brassdark" is still massively populated by flypeople. (before & after population change saves commited on the issue note)

http://www.bay12games.com/dwarves/mantisbt/view.php?id=7526#c35735

@Quietust mentions also that in the populations being loaded in, since the caverns is all 1 large area population pool with lots of poorly defined & overlapping sub-regions which are patrolled by FB's, all the creatures are loaded & drawn from the total caverns population each time rather than each local biome like the overworld. (link below to forum post)

http://www.bay12forums.com/smf/index.php?topic=117308.msg3668034#msg3668034

Same may be relevant for "Pointrose" as those individuals are replaced/removed out of the pool when the adventurer moves away but demand to be constant due to historical figures, requiring respawns like issue report 0005106. @Quietust themselves partially confirms this when he lured a soldier out of a loaded site only to have a duplicate guard take their place when he returned. (issue note beneath)
