Game Freeze Fractal Token [Investigating]

Event: Skoti Bloodline

My Planeswalker: Koth

Opponents Planeswalker: Garruk, Unleased

On the opponents turn castle garenbrig triggered, converting gems to green.  This conversion hit a Fractal token with 1 shield, thus destroying it before it could resilience up to 2 shields.  The game then froze, with the board not filling in the 3 gems that were destroyed.  I was able to quit out of the match, so it wasnt a hard freeze requiring a restart.

The battlelog for opponents turn says:

mana gain +7 green +1 loyalty

Castle Garenbrig was triggered
