Happened to come across the magic library in one of the apartments, and when I interacted with the books it said "It feels so nostalgic and soothing" but nothing happened.
I took a look in the playerlog and it looks like a "BladderChange" and "Maturity" change event try to fire, but the commands weren't found so nothing happened.
I would've sent this on the subscribestar but I don't have an account there.
