I found a flying shiny above the docks in Obol Plains yesterday and haven't been able to find another one yet.
Could it be possible to change the colour of those shinies, turning them red for exemple? Currently, they're blending with the stars in the area and at some heigh the air turns white, so they're really a hassle to see. I cannot really say if they have a spawning problem or if I just can't find them at all.
