I found that AI characters sometimes stand in the camp and keeps turning/spinning around to check their surroundings.

I attach a gif for clarity (sorry for not making a video, I will try to fix this by making one asap): https://1drv.ms/u/s!AqspxBbCcKg9hak_1vvoiOR6iW9wFw?e=exSsbd

Note that in the city of the base camp around we were fighting against some US units inside a building.

PS: I tried uploading the gif on giphy but it killed the image quality, so I have shared it via onedrive.
