A lot of bugs. Some scenarios I had to restart many times ... But not about that. Below, without divination - next signal aspect HUD
This is not about settings - 558 yd to "none" aspect - like on the picture. Ain't no color or the new-symbol-system. Looks this way all the time after update. Didn't check other routes.
Yes if the next signal aspect setting is set to NO then you see a grey circle without any colour. Change that to yes, and the aspect will be displayed in colour.
