I am in the 7.1 beta. I was really pleased to see you added a cumulative dirt effect for free flight, and updated the art for the front seats. Unfortunately the dirt is not saving between flights. This was my first flight on the newest 0.3.9 version. I immediately started a new flight at another airport after ending the first flight in the same sim session, and again the dirt was all back to 0. Also it appears it didn't save my datcon hours which were reset to 7.7 hours for some reason to start. I saw the patch note about changing the hours saving system to MSFS's built in one, so I was aware they were going to reset, but it seems the system is not working. After an hour flight and then loading a new one, the datcon still showed 7.7
