Got a bit of a big problem, only, I have no idea what's causing it. Since the latest update, vehicles are literally exploding at the beginning of the mission, or refusing to move! It occurs only when vehicles simulation is enabled via SQF (I think!). For a good example, please subscribe to my campaign on Steam and observe what happens - unfortunately, it's completely unplayable at present! http://steamcommunity.com/sharedfiles/filedetails/?id=576007033. It was running fine before the update. Also, it tends to happen only on the very first playthrough - but weirdly, it seems to happen consistently, on the very first playthrough!
