I'm aware of a current issue for 1.6.0
I will push a fix for it tomorrow!
There is a known bug involving switching from fast travel to non fast travel with Ezra, Juna will still do the job. (She really is better at her work)
Also, progression is locked without fast travel for Juna's new content at a certain point. This is unintended and I will release a 1.6.1 as soon as I can.
Work around: Enable Fast travel before starting Juna's content and use it for her scenes when you need to.
