Obviously the main part of the Omake can't be before the return of the Tenrou team. Putting the building issue aside, the very presence of Lucy and Natsu shows that very clearly.

But when I said "shortly before the Tenrou Group returned" I was talking about the flashback-scene that showed the sick Asuka on the last page (which played inside the Connells' house and didn't show any guild building).
