After banging my head against the wall for hours trying to complete Duality solo I took a break to get some food and went to the tower to clear full engrams and a full postmaster. After returning I went at it for another hour and eventually beat her but did not earn the triumph associated for Solo Duality. Excuse me but I'm not spending another night going for that because I "Need" to complete it all in one go.

What’s the point of this post? It seems you knew it needed yo be in one run, yet you broke your session into multiple runs. If you don’t do it in one run, then you won’t get the triumph.
