Weekly Quest offering no reward?

Since last night, my weekly quest has been offering me no cards as a reward. None of the objectives are completed as of yet, and I'm sort of worried that if I do complete them I won't get anything for it.

Is this a known bug? Any solutions?

Update: I completed the quest and received nothing... as far as I can tell.
