NewGRF vehicles are shown als airplanes

Sprite limit, what? I doubt you're hitting that, as the limit is currently around 16 million sprites...

I'm not sure but what I do know is that if you load a lot of NewGRFs at once, then vehicles from GRFs in the bottom of the list are replaced by question marks or random default sprites (like that airplane)
I once had a Shinkansen train made of skyscrapers, so I moved the Japanset up the list, and then my helicopter rotors were truck loading stations! Then I removed WAS, because it takes up so many sprites.
Maybe the sprite limit is smaller than previously thought? (I remember back when it was 16,000-ish; I couldn't even load DB Set, LV4 and Planeset at once back in 0.5.X)
