Fixed it.
Two solutions: Teach the creature the interaction, or transform the creature once.
First inorganic spawns a Monolith. It doesnt use any of its own interactions. Second inorganic teaches a monolith on the workshop the very same interactions again. A wonder happens. They use them. Third inorganic transforms the monolith generic into monolith generic2, literally the same creature, just a different caste. No difference between castes either. Still, it fixes it. The spawned monolith caste does not do interactions, but the transformed caste does use them.
