AI are Spotting Vehicles Through Terrain

Description

[Launcher version: 1.5.144923 Game version: 1.84.144923 Branch: main]

AI units are calling out targets on vehicles they can't possibly know about. I noticed this while playing many different missions with various mods and even testing this behavior in vanilla and the result is the same. A stationary APC behind a hill will get called out by my AI subordinates from over 700 meters away for no reason.

I have tested this on my other PC and the result is the same, with or without mods. See attached screenshot for example. I am holding still and my AI are constantly calling out a stationary APC and MRAP behind the hill.

This has been plaguing my game for a while and makes any operation with vehicles play out very awkwardly as infantry and other vehicles go into combat mode basically on mission start.

I had a friend test this and it's not happening on his game, why is it effecting both my PCs with no mods?

I observed this problem for a long time and was sure that this was an AI-modification problem, but I was wrong.
I am very glad that it is finally fixed. Thanks
