BO4T Beckett Brass (level 1-3) bug

If you gain control of opponent's creatures using the match5 ability of the node support, so that you have more than 5 creatures, and then try and replace one of your own existing creatures with a different one that you cast from your hand, there is a bug: the old creature is removed from the board, as normal, but then you are asked *again* if you want to replace a creature (I think because you still have 3 or more creatures in play).
