Same happening with me. This game is nothing more than a eye catching slide show atm rendered in 3D.
It doesnt have bugs but rather it is a bug nest itself. Sim update was supposed to bring some fixes but nothing noticeable has changed. Market placed has been launched to make more money buying airplanes that wont work. Responses upon logging tickets and contacting support are mere simple fixes advising to restart the game, reinstall the game etc. 80% of ones time is spent on trouble shooting rather than playing the game itself.
Bugs with less than 100+ votes will not be fixed any time soon, if ever. Because they’re not important enough for the community.
Seems to be fixed in the latest update. 
Fixed in SU2.
