In the first episod, in the mission where we have to rearm at ZA Connor with the help of Nikos, there's a minor bug:
Just after an autosave, the one near the destroyed car, where the doc have to check the driver's puls; if you die afterward and come back to this autoSave, the leader say everytime 'Kerry, where are you going?!' Something like that, meaning, I guess that I'm too far away. But in reality, I'm just beside him...
