Where the bug occurred:

Clicking on a selected card to fire a weapon did this:

What were you expecting to happen, and what actually happened:
I was playing the Class Event, Round 6, Battle 5, when I encountered this critical bug.
Playing at x4 game speed, I selected my charged Hero weapon (+9) Plumed Staff and was about to cast it on one of the enemies.
However, the mana on the weapon was depleted immediately (0/14), and I was unable to select the enemy, or maybe I selected the enemy, but the weapon did not trigger. I could only click on each of them, to see their troop data or card info - by default, each was showing the left side of the card, its ability. With no way to cancel this, I was effectively stuck in battle, had to retreat from it, and lost one of my last Sigil before completing the round 6!
For more information, check the screenshots above!

How often does this happen? When did it begin happening?
It never happened before for me. This was the first time that it happened.

Steps to make it happen again:

  • Play the Stormcaller Class Event at x4 game speed.
  • Play like a Speedy Gonzales.

I would really appreciate some official feedback about this bug.

Thank you.

It is safe to assume that this issue can happen with any weapon or maybe ability.
Perhaps there should be just a slightly higher pause between moves/cascades to prevent this from happening again?
