Was originally going to make this post about the 410's sight being replaced by this weird stripe. Checked a few other films and none of the gunsights show up. The 410 is the only plane that shows the stripe, though. Didn't make any changes to the game files or anything and all the sights were showing up a day or two ago.
Now it could be that the stripe is the outer ring of the sight I'm using, only it has taken it upon itself to grow to gigantic proportions and move way off center.
Just checked it offline and it works fine there:
