CS Extend Story Mode Issue

[Abominable K]

I'm playing through the BBCS Extend story mode on Vita, and it seems I've hit a wall in regards to unlocking Lambda's story path.  Internet says to beat Tager's story, but I've completed every possible route, including losing the Lambda fight.  Did they change the path in Extend?

Paths aren't changed, as they should be the same either way.
