The vehicle in cookoff status is still considered as target, but cannot be exploded.

• Arma 3: [2.18 stable]
• CBA: [v3.18.1 stable]
• ACE3: [3.18.1 stable]
  Mods (from AI mods only LAMBS Danger, I cannot describe the remaining 118 mods, because you'll get tired of reading their names and they are most likely not involved in the problem):

Description:

If "Advanced Vehicle Damage" enable, then the AI ​​will continue to shoot at the vehicle that already destroyed and currently cookoff. Apparently a vehicle in cookoff status is still considered as target, but at the same time, it cannot detonate until the cookoff time runs out.

Video example - https://youtu.be/kuIwjmVpXqg

In this video the AI ​​shot until it ran out of ammo!
I have not encountered such a problem with the previous version of ACE3 before. My previous ACE3 version was 3.17.0, anyway this problem appeared after.

Steps to reproduce:
play in Arma3 with ACE3 and heavy armored vehicles.
"Advanced Vehicle Damage" must be enable.
But I don't know how stable this problem is. It may well be that it only happens occasionally.

Expected behavior:
AI should not shoot at a vehicle that has already been destroyed. Because it's a waste of ammunition.
The AI ​​could shoot multiple times, but endless shooting looks stupid.

Where did the issue occur?

If subsequent enemy hits, after the Cookoff had already begun, could have added a chance for the vehicle to explode, then it would have simply exploded and solved the problem.

But this is not happening. As soon as the Cookoff begins, then the vehicle stops taking any damage, playing the full and equal duration of the Cookoff each time.

You can fix the problem, by adding the ability to continue to receive damage after Cookoff, which should lead to detonation.

From the template:

Make sure to reproduce the issue with only CBA and ACE3 on a newly created mission!

Can you attest that your numerous other mods aren't the cause of this? "Most likely" as an answer is not good enough - there are mods out there that change the most unlikely things. E.g. a visual effects mod that changes the rocket propellant time on the MAAWS and RPG rounds, making them fly further than normal, meaning the vanilla sights do not align with the trajectory anymore.

AI in Vanilla, as far as I can tell, will keep shooting at vehicles that have hostile occupants in them. In your video it's not clear if there are still occupants in the target vehicle. If there are, makes sense to keep shooting an undestroyed vehicle. If there aren't, then it's likely a mod interfering.

AI should not shoot at a vehicle that has already been destroyed. Because it's a waste of ammunition.

That vehicle is disabled at most, but it's definitely not destroyed. Destroyed means being a wreck and not being a threat at all, whereas if it's not a wreck it means that it could still be a threat.

But this is not happening. As soon as the Cookoff begins, then the vehicle stops taking any damage, playing the full and equal duration of the Cookoff each time.

You can fix the problem, by adding the ability to continue to receive damage after Cookoff, which should lead to detonation.

That's wrong, advanced vehicle damage will continue to work during cook-off. If you want to destroy the vehicle, you need to produce a lot of damage (15 >=), so it isn't easy, but that's part of advanced vehicle damage: If something is cooking off and you shoot it again, it isn't going to cook off harder.

This is not a bug, it's by design. If you don't like it, disable advanced vehicle damage.
