0003461: Underground animal people don't arrive from off-map to invade your fortress

Notes

Technically it's a child of 440, but they are slightly different behaviours so rather than being a dupe it's just "related", so it's better to branch them off the same parent. There's no appropriate advancement of 'time' for anyone other than people you control (Dwarves in dwarf mode, adventurers in adventuring mode). This causes the following 1. Historical figures (kings, liasons, people in villages, and in your case animalperson tribes) die of old age when you find them. 2. Historical figures don't properly repopulate when you're playing. This means that you don't get a new king or liason, villages can empty out entirely, and in your case animalpersons on your map die out entirely. Also, I should note that animalperson civs are currently local only. That is, there will not be a seige of animalpeople in the current release. Essentially you killed them all, there will never be any more. (In fact, I doubt this is really a bug, more of a misinterpretation, of animalperson behaviour)

(0013487) Quietust (reporter) 2010-10-23 21:49	The dev log entry back from January 9th mentions "underground invasions", and Toady's comment in the fix for 0003337 suggested that "irritating their cave feature" is supposed to trigger invasions.

(0013488) Logical2u (manager) 2010-10-23 22:24	I'm pretty sure that comment on "irritating their cave feature" is more along the line of "your fortress will not be invaded by lizardmen just because you built on their city. You have to find their city first.".

Off-map arrivals and repopulation of world gen populations are almost completely separate issues, there's nothing to suggest that this is linked to depletion of a map feature's abstract population, and invasions by underground animal people are definitely supposed to be a working feature. On topic: this report could use further corroboration. Has anyone ever seen underground animal people invade from off-map in 31.x?

(0023942) Quietust (reporter) 2013-04-13 10:21	I just remembered some research I had done a while ago, and its results may explain the problem here: Dwarf Fortress uses a system of timed events to handle special things arriving at your fortress from outside - Caravans, Migrants, Diplomats, Sieges, [unused], Megabeasts, Curious wildlife (e.g. rhesus macaques), Mischievous wildlife (i.e. gremlins), Flying wildlife (?), and Night creatures. The "unused" entry (ID=4) currently has no code associated with it, but in version 0.28.181.40d this event ID was used for Feature attacks (which is what caused the "rampaging tame feature creatures" bug); it's possible that the game is still creating events of this type, but the code for dispatching them is just doing nothing.

(0041142) Quietust (reporter) 2021-08-30 13:21	Possibly of note, I just discovered that version 0.28.181.40d contained logic for "irritating" map features when you dumped garbage into them, in exactly the same way that dumping garbage back in the 2D versions would trigger attacks from the Chasm. That "irritate" logic still exists in version 0.47.05, but it's not clear whether any logic still exists for acting on that irritation.
