Downloaded an update from simviation for FFX/SGA DC-10 and I noticed that I lost a lot of things plus behaivior of an aircraft was completly out of hand. First, with an update all DC-10 (that have been update) lost contrails no matter what altitude or temperature I set. Seconds, rotation beacon lights dissapeared. Third, is that on final approach the aircraft starts swinging from one side to another as if I am pulling the joystick all the way to the left and the suddenly all the way to the right and then suddenly all the way to the left and so on...Anyone else noticed those problems?

Thanks for you advice. But I had to revert back to the original files due to other problem described in my original post. Thanks for your help thought!
