Video here shows the 200 gold reward not being registered on server end.
Frankly this is all rather atrocious and I urge you to rectify this quickly. I have no idea if this is a recent bug or has been so ever since 1.03.
Considering the number of games in questmode I must have completed from 1.03 til now, that's close to 10k the sum we're talking about.
For your urgent attention please !
