Christmas tavern reward trouble, holiday cookie card back

[Nerevar-22482]

Similar problem, the developers are silent:

Didn't get a "winter veil treat" card back

I have the same problem: I completed a Gift Exchange tavern brawl and got a card pack instead of Winter Veil Treat Card Back. (I didn’t have it already) I hope the developers can solve this problem and we will be able to get this card back before the end of the season. I really would like to receive it)

[BUG] No Winter Veil Treat Card for first brawl win

UP! This problem is still not fixed.
