I was bored and decided to look some old IF screenshots because why not. When I looked at a TAM 777 screenshot, I noticed it was missing the 2 final registration letters over the cockpit. As I dug deeper, I found a screenshot featuring the tail, which, too, is missing the 2 final letters of the registration.
As someone with a very boring life and looking for most minor details when making my liveries (both for the Design your own airline or repaint thread and especially the few occasions I make liveries for RFS), I am 100% serious.
And yes, I’m well aware the chances of this being fixed are close to zero given how minor of an issue this is.
