'Pits of Nightmares' freeze [Fixed]

I got this freeze during AJTH/Nightmare of War/Pits of Nightmares, when Greg used his PW ability ("Brutality")

The game locked up completely, with no animations still running; after a while, I put the app in the background, and then brought it back, and the screen was now black.
He has a Dread Shade in play, I have Amass tokens created by Invade the City, and as you can see the Brutality PW ability was in the middle of resolving.
I don't know what support he has in play.
My support is a Colossus Hammer. I noticed in this game that Awaken mana did not count towards the +10/+10 bonus (I have two Coastal Discoverys full of mana in my hand, totalling 22 mana, but I think they are only contributing 3 mana each to Colossal Hammer) I have posted this bug in it's own thread but I mention it here also because I think it's possible the Colossus Hammer caused this freeze?

The game stuttered at the exactly the same point as it froze in the example above, but this time the freeze was less than a second and gameplay resumed as normal.
The issue when tokens are being destroyed is scheduled to be fixed in the next version.
If this issue persists after the release, please tag me here again so I can investigate this issue.
Thank you,
