First Time I saw this behaviour when I was exploring Vex basement.
After I asked Lystra to wait, and went down she appeared in a basemend and she joined me on the fight with the gangsters.
Second time I saw this behaviour was in Corath when I checked the Loner perk behaviour in Corath ring.
To describe this precisely:
1. I am ordering Lystra to wait.
2. Checking stats -> all skills increased +10% ( Loner perk work, I am alone ).
3. I am talking to the guy in front of the Nestor building. ( Challenge Nestor )
4. Appearing on the ring.
5. Checking stats -> sklls back to normal ( Loner perk doesn't work, somehow Lystra is back )
Not sure if this is expected behaviour.
If you need I can share my safe.
I already finished the game few times, no need to "check" / "fix" my saves.
During the game I was not using any character editors / etc, only original F2 + your mod.
EDIT:
After the fight with Nestor mutant, Lystra is with me on the dessert.
So it seems to be a bug, because I asked her to wait before fight.
PS.
There is a problem with amount of quests visible in a pip boy, you cannot scroll the list e.g. Albuquerque
PS2
During a game I saw Text above Lystra head like ( it is not exact words ): "I have to tell you something" but even if I asked her about it, there were usual text to choose.
