I think I found a bug. I can't send Veronica's kid to the artefact. I don't know if it's because it's her kid, or because I overfilled the day care maybe. I can't even interact with them, only Lil' Roxy. He just stands in the corner.
Edit: I think I didn't have enough kids at the daycare. now with a couple of new babies, I'm able to talk to Veronica's kid again. Still, seems odd that I can't talk to him when he's the only one there (aside from lil'Roxy)
