I would guess that those posts and messages were due to the timing of the backup.
I could always remake that topic, you could always repost, and you could PM Zeric again.
bustin would be able to tell you more precisely if it was possible to get them back, but I would think it either isn't, or isn't worth the trouble, sorry to say. If we did attempt to restore those posts, we may lose any posts we made just now, and that would be discouraging to others if they thought their posts were being removed multiple times. I would just leave things as they are and move on.
