I was playing with PudgyxPanda at the time.
On my side the whole battlefield froze, units stuck mid-animation and oscillating between 2 animation frames. None of the units responded to any commands, couldn't select or deselect any units either. Chat and the rest of the game worked fine and was fully responsive.
After a few seconds of the freeze I was notified PudgyxPanda disconnected, and I was then returned to the world map.
Attached log from that session.
