Did the invasion bug get fixed?

Finally confirmed invasion prevention even with the Loa Book linked in Zeta...! (It feels like using the Loa Book in Zeta, which has been implemented for a long time, is finally becoming properly usable) Well, the heroine got kicked out in this case though. I have a plot where the overly cute heroine dislikes me, and she gets eliminated very early on, but is this the intended way to play...?
