Question: When I list my own companion egg or butterfly egg for sale on the Grid Market but decide to keep it, what should I do?

Answer:

If you have your own companion egg or butterfly egg listed for sale on the Grid Market and later decide to keep it, simply disable the listing on the Grid Market before hatching your egg. To ensure it does not appear on the market after the egg hatches, it is always recommended to deactivate the listing on the Grid.
