What you were expecting to happen, and what actually happened:
Ironhawk making game glitch out and freezes end of battle so have to restart game and lose reward/lose gems and sigils
I will have lost 30 gems now, my stats to PvP and cannot complete my current delve as I will have to either restart or retreat
How often does this happen? When did it begin happening?
Has happened a total of 4 times. Started this am at 1am pst
Steps to make it happen again
Happens at random. Ironhawk appears to be the issue if the 3rd trait takes them out before a spell can be cast
This has already been reported and is under investigation by the devs.
Most players reporting it have Ironhawk (or Queen of Sin) and a troop or weapon that targets a chosen enemy, the hang happens when casting a troop/weapon that requires an enemy to be selected but Ironhawk kills all enemies first. In your case, I’d expect that it could happen if you cast Chalcedony, but you should be fine if casting Mountain Crusher.
One player has reported seeing the same sort of hang with other teams, apparently randomly.
