It has happened to me five or six times now, but as you've said I also got my army back... I've seen reports on others who haven't been so lucky though, but there might be a difference between PvE (which I'm mostly doing) and PvP.
This time I had several quality units in my quest army, so I really hope it's still there when the server is back online. One royal dragon + four heroes including the main one (plus some low level ogres and a few ballistas).
