I entered the T'Rang Base and now i stand in front of a kind of Controlpanel. For red buttons are there. Three buttons turn into purple when i press them, the lower right one stays red, no matter what i do. Behind the T'Rang guy i see three doors where i could use my T'rang arm, but the way is blocked an i can`t open it. Can anyone help me? Thx guys
