So apparently the covers "timed out"? Or the intermittent bug is still there.
No that's a new one.
The white cover bug is when you send personal documents via email or send to Kindle add on. They show up without their cover replaced by a white cover with the title of the book in black text.
I've never had sideloaded books via dropbox or USB lose their cover.
The only problem with sideloaded is they don't sync.
