I had several people complaining about the removal of the AI paths. I did this simply to reduce loading times and perhaps increase FPS. Considering that most lower spec computers will only be able to run this map with one vehicle at time, i thought this was a non-issue. Regardless i have fixed this by simply copying and pasting the ai_paths folder back into the MissionGroup folder. Be forewarned though, spawning multiple vehicles at the same time will have a significant effect on your FPS.
