[1.3.3066] Raider focus hive

[rimrik]

When raiders attack me, they always focus the Hives on the map before me which means they just go suicide to a Hive.

Does they went straight to the hive and ignore your colony (strange behavior), or does they just attack the hive by passing by (normal behavior) ?

[rimrik]

They go straight to the hive. As seen in https://i.imgur.com/ALuLHZB.jpeg, the raider spawned at the right and moved according to the red line straight towards the hive. I have an additional Hive spawn down below where multiple raiders have been attacking which is not shown in the image.

Additional information is that they attack the hive on purpose, even if the hive creatures are sleeping.

This doesn't seem to be a bug, though it does seem that the AI is being a bit silly. Essentially, raiders tend to heavily target your pawns and prefer to get to those pawns by utilizing any unobstructed routes. There are 3 tunnels that lead to where your pawns are now, one is blocked by your own door, another by stone, and the third (though a long way around) leads straight to your pawns without any obstructions. The only issue is that this supposedly "unobstructed" route is infested, which the raider AI does not take into account. Thus, they're funneled into the bugs almost every time. Completely normal Rimworld behavior though!

No, My colonists are completely isolated in that area, I've checked that it is an complete room, which it is. To get to my colony they have to mine the steel. Besides. Raiders spawning to the left go straight down to the hive when they are attacking to take suicide without needing to do so to get to my colony. Its like they get taunted by the hives which I think is not the intended behaviour.

Even then, raiders will dig through walls or mountains to reach you.
(That's why my front door is allways open for raiders).
And the raiders AI think it is maybe a good idea to dig from behind then to bash your frontdoor.
That the hive is at their way is just a sideeffect.

Should still not be considered valid since steel has 1500 hit points while a door has 160.
Also, this behaviour is also weird https://i.imgur.com/Uu9IOoe.jpeg since they literally just suicide to that hive.
They wait around and when they attack they go straight down to the hive instead of my colony. This is really weird behaviour.

Here's the save file https://drive.google.com/file/d/1kZUmQ4XOJeECcZ-TEVF0sUJ-uvf8UZpd/view?usp=sharing. It's not saved at a raid since I chose commitment mode, but might help anyways. (Have not tried on the latest updates since I abandoned this save since it felt to scummy)

Edit: Also wanted to add that if the AI think this is a good path, maybe it should consider things like hives before choosing a path to not instantly suicide?

Moderator Note:
This is intended behavior and in fact a defense tactic people have been using since they were implemented.
