I personally turned off "chase distant shots" on all personalities and tuned down hearing distance multiplier on Scavs. Now it is not as prevalent, but not totally solved unfortunately
I might do the same, but I'm actually getting used to the waves of terminator bots coming my way.
Because they either do that, or sit and spin in some far off corner of the map. I don't know if it's SAIN alone, or a combination with another mod. I tried to make sure that wasn't the case, but I could have missed some checked box somewhere or a true/false boolean in the config code.
The vast majority of the mods I'm using are QoL mods, like UI changes, graphics settings, hideout features, with a few weapon mods sprinkled in. The only mod I can think of that would directly affect AI would be a raid overhaul mod. I use SVM, but changed nothing for the AI for the above stated reason. Compatibility.
My list of mods merely existing at the same time might do it, but I'm not a coder/modder so it's just a guess.
