No, they're supposed to go straight to the vehicle. But rememmber that they are OFP AI Â
I tried to stop them from running around in circles by heavy scripting. But their behaviour depends on player actions as well as scripted waypoints. In playtesting they behaved like that 1 time out of 10. It's the best ratio I can get with my rather limited scripting skills.
this has to do with the engine in tonal they created, setting skill levels, scripts, triggers even a truck or where your men in your squad go can make the ai do different things. its preview and preview and edit, 100 times, with many different out comes.
