Either they forgot that, or they "forgot" that. However, while mid-edition retcons irritate me, I have grown to really dislike that greater/lesser-deity lore, so eh whatever.

In fact, personally, I think no god should have a true body, only avatars, their soul having become one with a force or philosophy.
If I remember correctly, the Hoard of the Dragon Queen modules were written by Kobold Press, not WOTC, which does make it very complicated to understand exactly what 5e's theology system is, considering this was one of the first official modules ever released.
