Since latest patch, game freezes during normal play. Froze twice in one game, was able to reconnect the first time, lost connection second time. Both times game froze during opponent casting animation.

Watched replay. Turns out I couldn’t reconnect 2nd time Bc opponent conceded while my game was frozen. 
Game froze again while watching a replay. All instances of freezing involves Ziran casting Gold Vitriol
I am seeing a freeze when heartseeker from BBS attacks. This causes me to force close and reconnect to get back into game.

I had an sort-of-freeze while playing against abyssian. I could still see their cursor moving around and it said it was their turn. The timer ran down. Then it seems like their turn started again, completely skipping mine. Not sure what caused it
