RPT logs when Locate Vehicle does not work properly.

- even if I get on the vehicle, Locate Vehicle is not completed.
- however, if the Locate Vehicle task is cancelled and the area of operation is determined by the Extract task, etc., the Steal Vehicle can be successfully completed.

please try with only CBA, and ACE3. the Sahara DLC should be okay as well. i cannot guarantee compatibility with all addons.

using CBA and ACE3, i've tried a few different objectives, and scenario types but the menu item is always loaded normally.

Example of an escape helicopter not being generated.
This happened on the first attempt.
CBA/Ace Only.

I believe that it is only a matter of probability (it only happens under certain generating conditions).

I have the following all about this test.
Ally: NATO
Enemy: Tura
Civ: Civilian

tried your settings with the test mission and still the extraction helo works normally. i'm really at a loss why it wouldn't spawn. without a way to replicate the issue its quite difficult to fix.

i tried also the extract with POW for extraction and as you can see it seems to work even with multiple attempts: https://steamhost.cn/steamcommunity_com/id/chazbotic/screenshot/2082409800769202384/

i did do some cleanup in a couple objectives to take advantage of some better check logic for completion: https://www.dropbox.com/scl/fi/hn6qwzpo4bi81dg889sgi/Dynamic-20Recon-20Ops-20ACE-20-20Altis-20TEST.Altis.pbo?rlkey=tlih1qy5b6jk6ra8hg9o54ren&dl=0

could you please try without:

@ACE_Particles
@ACE_No_Uniform_Restrictions
@ACE_Realistic_Dispersion

so doing some comparison between a working mission i had and the mission you gave the RPT from, i can see that the entry for:

6:05:11 A null object passed as a target to RemoteExec(Call) 'bis_fnc_addcommmenuitem'

is actually the server unable to process the target of the communication menu command - namely you, as the player group leader, is returning a null value somehow rather than a problem with the helo spawning.

i'm not entirely sure how that might happen if you're still alive and in control of a unit since in the command i'm using, i'm invoking the group via function is used in over a dozen places for other objectives and various triggers, which in theory should also fail if your group cannot be identified over the network.

@ACE_Particles
@ACE_No_Uniform_Restrictions
@ACE_Realistic_Dispersion
All of these are official ACE add-ons.

But even those were eliminated, and even in the state you wanted completely(Only CBA/Pure ACE), problems soon arose.

What is different in your environment than mine is
- factions
- Dedicated server Solo-play (all AI disabled on plannning)
- ACE Options Setting

i know they are official ACE options, however i do not use them to keep things simple when building the DRO ACE integration. my testing is with all default ACE settings, since customized ACE can vary greatly, but also used my more typical ACE settings too.

for factions, i used NATO/FIA/Civilians (and tried with WS using NATO and Tura), on Altis (and Sefrou-Ramal). i test in SP, self hosted MP, dedicated MP, and headless MP, with both AI controlled units enabled and disabled.

i'm unable to get the same failure mode.

i notice that you are using file patching. are you de-pbo'ing the pbo?

have you tried the test mission locally in SP?

file patching:
It is just used to load CBA User Config(cba_settings.sqf).

test mission locally:
I have not done any work on this test.
Dedicated MP only.

Perhaps signs of this have already appeared after Ready in Team Planning.
Sometimes Artillery Position is on the map but no support radio is added.
(Of course this is another glitch, as you know, and even if added, it won't work with Dedicated MP)

i've made a new function to detect and try forcing a living player as the extraction radio target. please see if the issue is still there. the chosen player will get a little dialog that identifies them as being able to call extract.

Thank you.

but unfortunately, it seems to have gotten worse. Extract no longer occurs after the task is cleared.

oops, that's a syntax error. i updated the mission to fix that:

thank you!

It is dangerous to assert, but it seems that the escape helicopter support radio is reliably available even if other mission elements are not working for one reason or another, as perhaps was the plan.

If this same thing could be applied to other support radios, I think the problem of support radios could be solved.
(Of course, in reality, support other than resupply does not work on Dedicated MP [no actual vehicles appear in the choices]...)

Meanwhile, the Steal[Locate] Vehicle (and possibly captive as well) continues to be confused by the task. Attached log is such a trial run.
Three tasks were created, but the one derived from Recon could not be successfully Recon'd[finally i cancel task], and in the other two, Locate Vehicle did not work properly.
