Looks like steam overlay crash. Callstack doesn't match. But final crash location matches.

Even if you solved it.. You now have the chance to help everyone else with the same issue.

Missing the model though, so can't actually be used :P

My problem is fixed! How? I do not know I watched videos and I restarted the game to see if there was always this error and everything returned to normal :o

This issue has occurred in the past but was fixed, and now is re-occurring.

I think this issue is fixed

Too much behaviors kill the behavior.

@MadogPL Tha's wrong. Game like Ghost Recon Wildlands had open NAT, and now strict NAT, on some providers, whatever the port you open.
The only solution I found is to make a DMZ which is strongly not recommended.

Skill Levels : forgot to check that. Would they evade if their skill level was increased ? I do don't think so, but need to test it.

That might have worked months ago. They know I've got good internet.

I dont mean a static IP Adress i really mean just a generic non static IPv4 adress. Just tell your provider that you cannot use your internet and if they do not comply that you will need to change the provider that mostly works

I can buy "outside" IP. But this is extra money. And it's like 1/3 price of the internet cost. Just to host Arma.

@oukej Thanks to research of @Alwarren we found out CUP's Harrier and F-35 are not "airplanex", but only "airplane" (due to some old issues that "airplanex" had with LHD, however that was not yet retested post Jets DLC). After changing it to "airplanex" vectoring with "vtol=4" works perfectly.

Hello @Wulf No MOD, always. Act, give any command to the AI, before he heals himself, and will tell you th, that he has cured himself.
This has been happening for a long time, from the first days of the release of Arma3. I could not understand why this happens until I paid more attention to it.

WHAT AM I NEED TO DO?

OK, so I did over 100 tests I think, though I stopped counting so not sure ...

Cool, I will gladly conduct tests in the editor (without any mods just to be sure) for this issue (set three tanks: 2 in LOS, 1 targeted but out of sight and command an AT soldier) and also for the other one issue I also posted recently (AI not evading their exploding vehicle).

I cant believe i didnt think about the mods. It works flawlessly now, i feel so stupid. Thank you so much for the help and sorry for wasting your time.

It's a Steelseries Arctics 7, Model number 5687923

Thank you for the report we will have a look at it.

Is it really at random? There isn't any specific thing that you do when the error occurs?

I don't unfortunately have much more info about the progress. When it comes to your specific error it is very generic and takes some time to find the root of the problem.

Thank you for the report. Could you please tell us what Headset you own?

Thank you for the report. We will have a look at it, though this is quite tricky and will need further discussion in the team.

Yes I am employed by BI and I am trying to figure out if there indeed is a problem with the AI. Also If you look at my profile there is a hint that points towards it. ;)

This is still an issue and has been around since Arma 3 was released. Any news on this getting fixed?

It appears to be my USB headset. I do not believe it is directly a 3.0 issue however as I tested it in other ports (not 3.0) and it still froze. I have attached the report.

Memory leak potentially

@PiepMGI
I can make a new car and use mods like real armor mod, but this topic is essential to distinct between body armor, not-armor-structures and character damage or perforation.

Huge topic.
You think about materials, but first of all, some vegetation are the best shield ever dreamed for units!
Note also, the global damage is totally weird and poorly related to hit parts. (you can fire at an offroad without increasing the damage value, destroying parts like engine, wheels or hull, then blow the car with a sudden full damage).
Check caliber/target/damage/hitpoints. it's nonsense!

Well, it seems this is intended:

I just tried again and realized I forgot about that. "vtol = 4" has the same issue as "vtol = 3", when you are on the ground nozzles are forced into vertical flight orientation. So it's the opposite of 1 or 2, it's like 3 in that manner, except it doesn't even allow for the minor changes that 3 allows (90-60° change or something like that), it's completely locked (at 90°) below certain height (~7m it seems).

I was just curious on the progress of this issue.

Will have to recheck the vtol 1 and 2 and get back to u.
Anyway vtol=4 should definitely have no restrictions - we've added that one for Xian - to have vertical vectoring as default/initial state and allow full range while sitting on the ground at the same time.

Hi @oukej thanks for the fast reply!

Could you create a test mission where you can be sure that it always occurs?

I confirm that these things happen randomly, I have not yet found any 'pattern' so to speak, but if it happens it is 100% consistent with the building, you just can't get the AI to move upstairs. is there a problem with the 'entry lod' to the building? As C222b reported, the units navigate like they were trying to access an ATLpos in open ground, ignoring the Z value.

Hey, thanks for the report.

Could you please upload here a video of the situation?

Fixed, thank you!

I see that you are running some mods could you disable them and try the showcase again if the issue persists?

Thank you for the report. We know about this issue and are working on it.

You might also try Profiling branch, it contains some crash fixes that did not made its way into a stable update or emerged afterwards and had to be fixed. You can use the profiling branch to play on the stable servers.

Does this happen with other data types as well or just arrays?
