[2020] How do I kick out a noble who missed her own shuttle because she had a mental break five steps away from boarding it?

Title pretty much says is. A countess wanted a few hours' shelter at my colony from a rabid squirrel and managed to get bit a few times on the way to my base, so she spent a little time resting up. As soon as the shuttle landed, I woke her up and right-clicked the shuttle to tell her to board it, and she started to move towards it.

But she had a mental break five steps away from the shuttle, and turned around and started sad wandering. She kept sad wandering for more than 15 hours as the shuttle pilots I guess watched, until the shuttle left without her.

I failed the quest and got -5 relations with the Empire, and the quest failed text said the countess would leave on foot. But she didn't. When she woke up from the sad wandering, she kept participating in the colony like she's been here all along. But I can't support the requirements of a noble right now! How do I kick her out? Will she actually leave eventually?

edit: I ended up doing the ol' "false freedom" trick. Waited til she started setting fires, arrested her, then broke a part of the jail cell. She happily ran to her freedom...or really, my freedom from her.
