When dinosaurs are released guest are running away, which is ok. But when the bunker is open, they seem to follow only the pathways. As if there would be a sign, not to touch the lawn. Even if the shelter is 10m away, they tend to run towards the carnivore eating them, and making a 200m extra run on the pathway to follow the path into the bunker. This is a glitch in the game, and bunker entry's last waypoints should be rearranged by minimizing path distance.
