Hm so I wont point in a wrong direction.
The error itself Iam sure, are a huge calculation for distances. And the error say its too much - and break this calculation. This error Iam sure not come ones. And in this case at a point its enough for arma and its crashed.
I know this error too in older Missions and you can read in BI and other forums a little bit about it.
AiA.
Here I really dont know. But I guess this cannot be the problem, I mean the map itself.
But maybe someone here correct this.
On the other hand, only a hint but sooner or later everyone must change to CUP.
Latest after the Apex release and such more Objects for Maps and so on.
They have Trees and Bushes and much stuff from A1 and A2 for the Editor, its alle more future Arma relevant and really good job what the guys does.
So maybe, but i didnt think it really, a mappack change brings a solution.
What you can try?
Its work, like always :)
Make a new Mission on Takistan with AiA. Name it and save it. Load your older Mission, zoom out, mark all Modules objects and so on, and strg+c to clipboard. Now load your new clean mission with nothing in.
Now paste (strg+v) all in the clean new Mission BUT dont save now.
(When you have Objects placed like a FOB then all this is propably not at the same place. You can solve this when you mark all things and then zoom in and then look for a number or a point at the map where you can point your cursor and now you copied it. Same way when you paste it, you need zoom in at this own point and direct your cursor above and paste it.)
The point is you dont preview or save it in the new copied mission. Now you delete all this things they are not so relevant for this test. So that you have a "cleaner" new one. And then you hit the first time in the copied new mission the save button. Arma Iam experienced, delete - saved not everytime correctly changes in a mission.sqm. In all time in editor I remember that a new mission.sqm solved obvious errors, sometimes.
Maybe its better in 3den, but this is the next thing. Try this all in 2D with AiA, only a hint to avoid more obvious problems to beginn.
The longer version from this is.....load only one mod after another to your new mission and build it complete new again....
I really cannot explain why it should be the Map itself.
And I see nothing in your modset that explain for me the error. But i dont know all from this list.
I know this error from older missions as example with advanced ballistic. And in this case was the module initialized twice everytime the mission starts. But no second module and nothing, solved only with a new mission.sqm. RHS brings this error sometimes too but with a ammo error in ACE combination.
It is dedicated server?
ASR AI should be on both sides, specially on server when Alive spawns in with -filepatching startup and userconfig loaded (see RPT).
When you have AI in your group this can be obvious issues and performance impact for the AI scripts and server communication, then when AI are in your group they transfer to your client and your client now do the calculations and send it to the dedicated client/server.
Is Pooters addition good? i love to play with AI and such mods like ASR and so on.
