It could be that the space you selected for her does not meet the requirements. I think they should only move on patterns if there is no other available space. If you still want me to come over, I can.
I would create another space where she could move that seems to have enough space and check if she moves there or still ignores the rule
If she moves there, you know that the issue is the choice you made for her plot and you need to prepare a new area.
