What did you do?
I loaded an autosave to setup defences (forgot and went afk) to fend of an attack.

What happened?
After fending of said attack I finished up and left Gleba. Some time later I checked in map view and saw a huge pile of enemies "frozen" just outside of my tower range. Building Turrets next to them only caused a couple of them to attack. However sometimes a couple of the wrigglers make it through the pile and attack.

What did you expect to happen instead?
The Enemies to attack and not get stuck, piling up endlessly.

Does it happen always, once, or sometimes?
After killing them off and continuing to play for some time a new pile of Enemies formed.
However visiting the Planet and walking close to them "unlocks" the whole pile.

Edit: Screenshot from the second smaller pile that formed in a different spot
Edit2: It seems like the first wave of an attack gets through and fights the turrets. (Mostly the Stompers and some Strafers). As soon as the Enemies in range of the turrets perish, the rest of the attack wave seems to freeze/get stuck and won't move.

I have the same issue in version [2.0.12-2].

can confirm and they wake up if a player or spidertron come near them.

They also don't seem to heal when they get stuck like this; I have a few strafers stuck just outside my defenses currently, and one is still on 72/2400 hp. They must have gotten slightly out of range of the rocket turrets while strafing, then just gave up and froze.

I also had a new wave walk directly over the stuck enemies and they didn't wake up to join, which is surprising.

[2.0.13]

- (edit) Just had a tesla turret chain and kill the 72 hp frozen strafer. The other 2 stuck strafers next to it are still stuck.

Same is happening here on the version 2.0.13-1, they are getting stuck near deep water and just standing there, have many of those around my factory

I have noticed the AI is not active when my character is not on the planet. Once I land on the planet, all stuck AI out of sudden come active.

- I have no tanks and/or spidetrons on Gleba.
- I have also noticed that bitters on Nauvis are very passive when they hatch from (spoiled) bitter eggs when there is no player around. Maybe it's related.

Same here. I've noticed that Gleba enemies just got stuck mid-attack and didn't react to new turrets being placed by bots.
Also, I confirm the point about passive hatched enemies on Nauvis. Also, for some reason, only 5 big biters spawn from an expired stack of 100 eggs.
I've attached a save file with the proof.

Encountering same behavior for all enemies on both Nauvis and Gleba

I haven't even went to a new planet yet and am seeing this behavior. I see it when I'm simply "far enough" away from the enemies - when I get in range (I'm not sure what that range is at the moment) the biters become "active".

I think the whole time the enemies are indeed working and are being shot at by my turrets, I just don't see the animations or anything like that until I get close. I only know this because when I get close, a bunch of new corpses (that weren't there before) get created. I also see biters "popping" into existence when I get far enough away, but the sprites do not animate.

You can see this in my current save here: https://www.dropbox.com/scl/fo/dnegh49x ... dkhnd&dl=0

If you leave the player character where it is and remote-view to the bottom-left corner of the map, you can see that the biters aren't animating. Quit the remote view and walk over there, and you can see them start to animate again.

Same in 2.0.15. if the base is in radar view it looks like only pentapods that are associated with the attack get stuck, but around the base regular security moves normally.

Same thing, 2.0.16, remote view, only pentapods. Other attacks occasionally pass the "stuck" enemies, but the enemies don't get unstuck. Remote driving a tank doesn't even unstick them. For me, only player can unstick them, though I haven't tried spidertron.

Far away enemies being frozen is by design, for performance reasons.
(Maybe they should be unfrozen as the players looks at them, if in direct scanner range, or would that be misleading ??)

The formation of whole new islands made out of pentapods... is probably not.

That's a bad assumption. Yes, for performance reasons, bitters who stand around the bases and do nothing are usually turned off (all links <2.0). But here on Gleba, an attack is launched and half of the units freeze in front of the base. The bug can be repeated. I made a save about 20 seconds before the start of the attack on Gleba (look for the "next freeze" label). I tried reloading it several times and it always ended up freezing 10-50% of the attack units. A "pollution" attack should not be subject to performance limitations.

Right, I should have been clearer about this, but

reported the first one, not the second one.

In some of the links I gave they do mention pollution attacks and settling parties work just fine for Nauvis.

(And these behaviours are probably related ?)

They also wake up upon receiving an artillery shell to the face, at least in a small radius of the strike.
EDIT: Or even having a shell fly over them to a more distant target

Can you blame them ?

I had this happen as well. I had a radar that was destroyed but continued to show the area for a long time. My guess is that the game thought that they were no longer visible and disabled the movement behavior. But I could still seem them using the remote view.

Ref 118347 Stompers on Gleba stopped working, 119882 Pentapods freezing, 121345 Gleba enemies stay frozen when about to attack, 121467 Stomper stopped moving, 122401 stuck enemy, 122652 Wrigglers frozen mid attack, 123850 Pentapod swarms lock up and stop moving, 123868 Enemies on gleba stop moving in certain area, 124349 Wrigglers Getting Stuck/Frozen in Place, 125650 Large amount of enemies frozen.

Examining them with show-debug-info-in-tooltips shows their StopGathering tick number is in the past.
It seems they were gathering, then during the time they were supposed to stop gathering and start the attack they were asleep for some (probably performance) reasons, later woke up, but the end-of-gathering logic assumes they were always awake?

Someone on discord reported that gleba enemies refuse to expand into the zone of a roboport, even if it has no power, which is easily exploited. When your gleba enemies "freeze in front of the base" does there happen to be any roboports nearby to corroborate that theory? Or maybe they were mistaking some other restriction on expansion on gleba for roboports.
