0006220: Depopulation of underground animals when playing Adventure mode

Notes
(0023959) Knight Otu (manager) 2013-05-07 02:52	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. ..."

(0025539) XXSockXX (reporter) 2014-07-10 08:26	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.

(0025579) thvaz (reporter) 2014-07-10 13:14 edited on: 2014-07-10 13:15	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

(0025592) XXSockXX (reporter) 2014-07-10 14:05 edited on: 2014-07-10 15:52	I tested it in 2 worlds, results are here: http://www.bay12forums.com/smf/index.php?topic=117308.msg5458529#msg5458529 [^] 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. Results are here: http://www.bay12forums.com/smf/index.php?topic=117308.msg5458697#msg5458697 [^]

(0026201) Talvieno (reporter) 2014-07-13 14:03	Possibly related to 0007216.

(0026651) XXSockXX (reporter) 2014-07-16 11:22 edited on: 2014-07-16 11:23	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).

(0029990) smjjames (reporter) 2014-09-06 10:03 edited on: 2014-09-06 10:05	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

(0037046) thvaz (reporter) 2017-11-27 05:03	Still happens as of 0.44.02: Pocket World, before: 12846 gorlaks 6916 trolls 1770 giant cave spiders 20627 elk birds 6721 giant cave swallows 6613 naked mole dogs After an adeventurer walk around one day: 8715 gorlaks 4768 trolls 1254 giant cave spiders 13616 elk birds 4405 giant cave swallows 4284 naked mole dogs

(0037047) FantasticDorf (reporter) 2017-11-27 05:42	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.
