You shouldn't need to trigger this event to go to New Eden.
Is this for the 'Hot for teacher' part of her substory?
If so, you can either use the console to get someone below 50 skill eg
State.variables.lacy.skills.farming = 49;
or move to the next stage. That step is merely there to demonstrate you can spy on her, there's no lewd there or major substory development.
State.variables.lexi.events.teachspy = 1;
.
In fact it's short enough I can even screenshot it for you.
I'll remove the step in her tracker in the next update, given the restrictions of it and the lack of importance it has to her substory. It's only flavor content, really.
If it's not that step, let me know!
