Thank you for the response! I have retested the scenario with CBA removed and minor changes. I made myself the leader of the AI fireteam and gave them a waypoint to move inside the livonian building that replaced the Altis building using the hide object module. I then experienced similar behavior with AI walking through the walls or not attempting to move inside. I then move the house a few meters back, away from the module and they have no issues. This has also been replicated with buildings from the Global Mobilization DLC. Let me know if you need any more information or would rather have me create a new task.
