The team pushed out a fix that should take care of this, though it may take a few minutes to reach everyone. You may also want to restart your game when you have the chance as well, though if that doesn't resolve everything, do let us know.
Will there be a compensation? My best champs were stuck in that quest and with no solution in sight I had to quit to join AQ. We should at least get a few energy refills.
