Why the Unreal Engine 4 Sizzle Reel - GDC 2015 youtube video has been taken down?

This link ?v=5orTzUuZPOg
was working until recently that youtube says “This video is private”.

Regards.

Dont know why they did it, but here is the new one: ?v=g_MY5oP-ks4 :slight_smile:

I posted this question because I couldn’t find the re-upload in their channel… It should be uploaded in the past hour :smiley: … thanks.
Maybe they just have a typo some small detail they had to fix
I couldn’t notice any difference with the old one from IGN copy :wink: ?v=MOa_QdGGrro
