Battlegrounds bug

Hello,

I’ve encountered a bug in Hearthstone during a Tavern game.

I picked a small treasure that said it would upgrade into a big one when I buy a big treasure. As a result, I ended up with two copies of the same big treasure — Embrace of Light. This caused me to receive 4 spells at the start of each turn, which can only be used if I have a Battlecry minion on the board.

However, there were no Battlecry minions available either in the Tavern or on my board. After 3 turns, my hand got completely filled with these spells. I couldn’t buy a Battlecry minion because there was no space in my hand, and I couldn’t sell the spells either.

So I had no possible actions, skipped multiple turns, and eventually lost the game because of this.
It feels like a bug or at least an unfair situation in the game.

I have screenshots to support this if needed. Please look into it.

Thank you!
