Freezing trap bug

[Rhasimir-1573]

Acknowledged to be a bug, with a possible workaround in the mean time:

@Kerfluffle-11372

We’ve also seen reports that minions sent back to hand from Freezing Trap are unplayable. We’re working towards a fix for this in the future, but there is a workaround in the meantime—while clicking on the card does nothing, you can drag on the card in order to play it.
