After downloading the Na'Vi vs Ehome Final, I realised the replay was bugged. Fog of war not moving with heroes, Furion in civilian pose and naked, Invisible Puck, etc.
Anyway, that's not the bug I want to report, that one must be caused by some patchs or whatever.

The bugs I encountered are, after downloading a new replay [ID : 42997] :
At the Pick phase, Na'vi and Ehome were still the team names.
And the four Audio Channels with the International Commentators names are still selectable ( But silent ).

It seems that the game doesn't clean the replay UI after leaving a replay.
