Is Beckett Brass broken?

I just played a match using Admiral Beckett Brass and she refused to steal creatures. I had Captain Lannery Storm, Timestream Navigator, and Admiral Beckett Brass on the battlefield. I attacked and damaged my opponent with all three creatures yet she didn’t steal any of the opponents creatures ( Demondord Belsenock, Cabal Paladin and Chainer’s Horror). This happened for several turns in a row.

Has the card been changed? It used to ask me what creature to replace with the stolen one then destroy the one I didn’t choose.

I think you have reported a known problem.
