It’s fixed!! Received the latest update through Steam, cleared the cache file, ran Black Death, and those friggin’ blue lines are gone. Totally Flipping Awesome! Also noticed that the ground impact explosions are back, as well as some additional graphic detail (2 burning impact craters in the runway, for example). Average frame rate is 1fps lower than previous, most likely due to the additional detail.
Thanks, luthier! Thank you, thank you, thank you
