Summary0003685: Goblin squads invading a fortress will kill their non-goblin squadmates, sparking loyalty cascade
DescriptionI had an incoming ambush of goblin squads from the civ Dread of Trails, with three humans mixed into the squads. Upon spawn on edge of map, the goblins immediately attacked and killed their human squadmates. From checking Legends afterwards, this apparently spawned a loyalty cascade, making the goblin group The Clean Malice an enemy of its parent civ.

Afterwards, ambushes would immediately produce infighting within the squads, all at the edge of the map, until only one or two goblins remain alive per squad.

I was not able to save before the ambush with the humans but the provided save below is during the second ambush, immediately after the goblins (this time with no humans) spawn on the map.

I am not sure whether all the goblins are members of The Clean Malice, or if there are non-Clean Malice goblins mixed in the ambush squads.
Steps To ReproduceLoad save from [^] Goblin ambush is at edges of map, killing each other until only one or two per squad remain.
Additional InformationThis is a 2x2 embark on a world genned under 31.18. The only mod present is changing default site for dwarf, elf and goblins to CITY, in order to have non-human towns present in adventure mode. I have played several adventurers in this worldgen before starting this embark, particularly, one human adventurer raided several towns belonging to the Dread of Trails in 388.

It's possible this is an artifact of my particular worldgen (i.e. having an adventurer massacre goblin towns before embarking) but if this happens to any goblin attack with ex-abductees, then it will significantly lower the difficulty of goblin invasions.

That is actually pretty sweet. Different groups breaking off the main civ and all, even if it is a bug.

Digging deeper into legends, this is how I think I managed to produce this situation:

1. Mod your game so DEFAULT_CIV for goblins is CITY instead of dark fortresses, so goblins spawn with human-like towns.
2. Find a goblin civ and a town/hamlet founded by a subgroup of that civ. Ideally this town would be close to potential embark sites for your future fortresses, and invaders would be coming from this town.
3. Create an adventurer from a civ at war with the goblins, and have him get some reputation (enough to be able to hire four or five companions).
4. Go to the goblin town you picked with your adventurer (make sure you have free slots for hiring more companions) and attempt to get a random goblin to Join your group. This should be possible if your adventurer has not killed any goblins yet (and is unknown to the goblin civ).
5. Watch as all the other goblins pummel the hapless gobby you hired. Watch them kill each other afterward for murdering the goblin.
6. ? ? ?
7. Profit! *

*"Profit" in this case means goblin mayhem, and a relatively safe environment for fortresses in the area, as goblin ambushes will reveal themselves as soon as they enter the map, and goblin sieges will soon devolve into vicious free-for-alls.

It should be possible to produce similar human or elven loyalty cascades if you can spawn adventurers from civs at war with them.

Ok I was wrong, apparently someone else has this bug (goblins killing human squadmates) here: [^]

so maybe it wasn't triggered by my adventure mode massacre. Must test with a new worldgen.

I'm noticing this bug as well, also occurs in Deon's Genesis mod with the demon race.

I started a new fort (also under 31.18, same worldgen as before) and it looks like it's definitely an issue with human squadmates in the goblin squad. Even without an adventurer stirring things up, goblins will attack humans in their own squads, descending afterwards into a loyalty cascade until the ambush squads are decimated.

In this new fort, the first two ambushes did not have any human members, and proceeded normally (i.e. coming out of stealth only when discovered). The third ambush had a human member in one squad, and after the human was attacked, the other squads also started fighting with each other (even if they did not have any non-goblin members).

The only mods to the game were setting default site to CITY for elves, dwarves and goblins, and changing PET_EXOTIC to PET for a few animals.

Here too - two goblin squads immediately revealed themselves, killed a member each (a goblin and a dwarf) and ran away. I'm running Deon's Genesis.

more corroboration from other players: [^]

As a wild guess, abductees might retain membership in their old civ entity and are not properly "inducted" into the goblin civ, but properly become members of the town where they are relocated. (i.e. abductee from Innocent Alliance becomes a member of The Clean Malice (subgroup), but not a member of The Dread Trails (civ)) and thus are immediately seen as enemies by Dread Trails goblins who are not from The Clean Malice.

Edit: The infighting seemed to go away after five or so years into the fortresses' life. Possibly the Clean Malice had no more goblins left (all able-bodied goblins killed in ambushes or sieges) and no longer contributed goblins to the war effort? After this point ambushes appeared from stealth normally, and sieges worked correctly, with no infighting.

Unlike the others I have this happening in 31.18 with a completely unmodded world. It all started with a ambush that had human members as others have reported. Previous goblin-only ambushes worked fine.

Just experienced this one myself. Screen immediately zooms to the ambush as it arrives (thrice, in this case), each with a few goblins and a single dwarf. "Strange," thinks I, "someone must have REALLY good eyesight."
Assign soldiers to kill everyone, three seconds later there's blood all over the place and all the ambushers run away. Combat logs show that the goblins started fighting the dwarves.
Previous ambushes with nothing but goblins went as per usual. Am yet to experience the "loyalty cascade" that causes a free-for-all, since no other enemies have arrived yet.
Using custom, home-made mod that inserts a new race, civilisation, and some items and materials. No adjustments to existing raws.

V0.31.18, naturally.

I'm having this issue too. v0.31.18, unmodded.

This is fort 0000002 is the current world, and I've played a few adventurers who fought goblin bandits. The first two ambushes on this fort proceeded as usual. The current one was revealed on the edge of the map and the squad leaders immediately started fighting their soldiers. Unlike the reports above, all the invaders are goblins: no abductees of other races.

...And now, with the next set of ambushers, I have combat logs like "the Goblin Swordsman stabs the Goblin Swordsman with etc."

Only one goblin survived the complete free-for-all.

I've been experiencing this issue too, on 0.31.18 unmodded.

I get 4-8 pause events with "An ambush, curse them!" with goblin squads appearing around the borders of my map. The squads then turn on themselves. If any goblins survive the squad massacre, they will then run for the nearest survivor from another squad and proceed to duke it out. This happens until there are 0 - 1 goblins left on the map (typically the last survivor dies from injuries).

Though entertaining, this is hampering my attempts to test my drowning trap.

I can confirm this bug. Clean install. 31.18 generated world. No previous adventuring.

4 ambush squads arrive in short order. Every time they are immediately announced and uncovered. 1 Dwarf in each squad. He gets killed, and goblins commence killing each other.

I have that happened to all-goblin ambush parties as well. What I noticed that most of the time, the ambusher that gets attacked by their teammates is some kind of historical figure, a general or war leader or something while the rest are just generic generated goblins.
Is it possible that this is caused by the new [local_banditry]-tag? I noticed in adventure-mode that it makes goblins attack creature from the same civilization if they are from different sites. Maybe the ones that get attacked just have a different site membership than the rest?

I am not so sure this issue has anything to do with multi-race 'goblin' squads. I don't think I've ever seen a human, a dwarf or an elf in an ambush squad, yet the goblins consistently choose my home for their own form of gladitorial combat. There's rarely more than one or two left for my military to clean up.

It's not a bug, it's a feature! Imagine getting kidnapped as a slave civ. How do you react revenge? Wait it out, right? Til the time is right. What better time to exact revenge than when you are fully armed, on the doorstep of your enemies enemies and nobody is watching! I am SPARTACUS!
Quietust (reporter)

Other reports suggest that this may also be happening with goblin-only squads where the leaders were original members of the civilization - the remaining members of the squad are created out of thin air (as has always been the case), and it may not be setting their allegiance properly.

I've actually encountered something like this in adventure mode .34.01: a goblin attacked my human adventurer even though they were from the same human civ.

Here's one in 0.40.10 adventure mode. Initially I thought it was some kind of battle since I saw fighting announcements of dwarves fighting goblins, but they were all hostile to me and occasionally they'd attack each other. A bit later (after I had some fun with the recruits, who weren't particularily dangerous) when I decided to try and sneak in to see if they were camping or something, I saw a bunch of the dwarven recruits attack one of the goblin soldiers, and there were other fights earlier.

In 40.24 goblin army attacked my fort while I was retiring it and spawning adventurer there. So far I have seen only fights of goblins with trolls and goblins with dwarves, trolls seem to not attack anyone or just goblins.

I'm not seeing this in 42.xx, invaders have mixed groups and seem to get along. Can anyone provide a current save that still demonstrates this issue?

Within 0010338 goblin outcasts underneath a city/hamlet (unclear) were hostile to each other actively fighting & attacking the adventurer player on sight. Likely from different goblin sites & groups of origin.

Slaves took in by goblins (with different core values as they are taken from enemy sites) as cited by summary are likely being killed by the goblins [ANGER_PROPENSITY] value which causes them, a trigger being disagreements & arguements.

At random, arguements send them into a fit of rage where they attempt to murder the nearest person (usually the person they were speaking to) until they calm down frequently triggering loyalty cascades with those nearby.

A review of the requirements needed to activate a goblin's anger could be required, so that they don't attack their friends or acquaintances just by a imbalanced values comparison without good reason.
