Whenever I have talent points available and I am spectating from death, I see my points displayed in the talent view (tab) of the character I am spectating. To confirm I asked Sunborn if he had 5 available points to spend and he did not.
Private bot match - Grey Talon went into a horizontal orientation, I missed what triggered it, perhaps his number 2 ability or perhaps receiving a spell cast from an enemy hero. I could freely move/cast/etc in this orientation and other clients could see that my character was in this orientation.
Seven's character model during his ultimate ability (electric skeleton model) persisted through death only in my client. Death occurred right when casting the ultimate. Model stayed in skele form (only in my client) at least until next death, or maybe it was until casting ultimate again...
