I have major problems

OK my game has gone mad it all started after I finished the meet the Oman mission. After I got back to base and launch again after a couple of seconds I appear by the Oman base and this Guy is telling me to travel with him to the training ground and he keeps repeating himself about 20 times .Then after the mission where you get the ship at the end and they say they will contact jafs to pick it up, when I get back to base the ship isn’t there just the tug and command section . Also after the mission with jet and the Kong in the cut scene at the end my home base is there instead of the base I was just defending and it is still there when ever I launch. I have the latest version of the game and I haven’t got a clue why it is going wrong please help I love what I have seen of the game so far and want to complete it.
