Having re-read your post, I think the goal gets completed when your serpent hatches. Occasionally, the order of the goal quests change due to - er, well okay I don't know why, but that might be why you think the goal has gone.

I don't know why the goal no longer appears on your list, but I have hatched dragons before a particular goal quest has been presented to me and I know that when the goal quest does appear that the goal gets completed, presumably because I always keep new dragons. I have placed a genie in the Trading Portal because it was a repeat, only to regret it because a goal quest asks for 3 of them - still haven't completed it even though I've had 3, just not at the same time.

Hope that I have helped (and not confused, my speciality), GL.
