Freezing

I am as willing as any to help developers improve this game, but the Moderators are just plain onerous.
My game freezes. I've lost points, ranking, mana, and patience.
So I go to the "report problems" posting topic. If you click there you get redirected to a generic area where you can wander aimlessly trying to post your problem with no reasonable way to get this done.
I have a screen shot that I'd like to post here, but I cannot. There is no way to do so.
This has happened several times now.
I have Sigarda, Heron's Grace. When you have 3 Creatures and you activate Sigarda, the game freezes.
I've had more than 100 life with my Opponent down to 20 life or less, and the game freezes. I have to shut the game down and lose the game, life, points, mana, crystals, patience and respect for the Creatons who manage this game.
