Hello,
i found a bug on the german client of hearthstone, involving the card “Gold Panner” (2 Mana, neutral minion, At the end of your turn, draw a card).
When the end of turn effect is triggered, and a card is drawn, Gold Panner has some voicelines. It seems that in the german client, this sounds are in a different language (english). All other sounds of this cards seem to be fine.
