Fertile Footsteps (Beanstalk Giant's "Adventure" Side) Asking To Replace Creature [Investigating]

DabeDotCom Posts: 4 Just Dropped In

How come ((Beanstalk Giant)) — or more specifically, its Adventure side, Fertile Footsteps — is asking me to Select a creature to replace? FF is a spell, no? (FTR, I haven't verified whether or not it has anything to do with having an Omniscience in play...)

If I tap "Not Now", it just keeps popping up again and again.
