I've been re-reading Starfire and Stormbound and so far have found three things that didn't make sense.
1, In Starfire on page 54, it said that one of Mossberry's parents was named Windheart. ("Mossberry, filly of Windheart,") But then, in ROTR, Dewberry gave birth to twins which she named Thornblaze and Windheart. Hmm...
2, In Starfire on page 67, Morningleaf told Star how some of his supporters would meet at Poppyfeather's Mirror, (a waterfall) to discuss how to protect him. And in Stormbound on page 219, Summerland told Morningleaf that he is "Summerwind, colt of Raintree and Poppyfeather of SunHerd." Something to think about.
And 3, In Grasswing's Story at the end of Starfire, he described Graythorn, Grassfire's colt as a dark silver colt with pale green feathers, creamy mane and tail, full blaze on face, and one white sock. But in Graythorn's description at the beginning of Starfire, it says, "GRAYTHORN- Palomino colt with violet tipped gray feathers, thin white blaze and two hind white socks." Wait... what?!
Are there more things that you found in the books that don't make sense?
