AI will go through animation of talking to check point guard, turn in place toward vehicle then restart animation of talking at the truck. After going though the animation again, the AI turn 10 degrees left or right and restart animation. Will always look in trucks direction (even if moved) as if meaning to head to the vehicle but failing to do so.
Have tried different AI difficulties from game options menu, no effect. Positioning passenger door right next to AI so that if the path finding wouldn't have to do moving, just get into the vehicle. Have also tried to nudge AI away from guard with truck in order to break talking interaction with guard by distance, like many other interactions in the game.

Problem still happening. Would consider game breaking as it's stoping the campaign from continuing.
