Hey everyone,

We released a rather large patch today, and we’ve had a few bugs pop up as a result. We’re working through these bugs now and should have an update for you on each in the next few days. If you encounter a bug with this patch, let us know in this thread.

  • We’re aware of and working on a visual bug that persists on the board after a Corrupted minion has been destroyed, transformed, or otherwise removed.
  • We’re aware of and working on a bug that is causing unlocked Duels Hero Power and Signature Treasure choices to revert to default Hero Powers and Signature Treasures after they’ve been selected.
