Node 2.2 frozen

I had 2 freezes during the Trial of Zeal where the only thing i could do is quit or review the battle log. I even had a freeze in Rate Rarely Fair. no idea what s causing it.

Exact same thing happened to me in FiRF. For me it happened on a match during a cascade caused by beginning of turn gem conversion. 

Same here: had two frozen games, both on node 3.1 of the Trials of Cycling and both while I was cycling something (not that I've been doing much more during this event...).
Sort it out please.
