I had my child sim try grandparent candy and he lost a tooth/got a tooth fairy certificate in his inventory. Below is the popup/inventory item I recieved.

I didn't expect this since I installed the patch that removed that functionality from the game. I know the patch is working in my game as this sims brother had a loose tooth prior to the patch and that moodlet went away after the patch was installed.

This did happen on a game with mods but since it seems to be a random chance event I wasn't sure I could recreate it "on demand" in a vanilla game and thought it was important enough to report since I understand functionality related to losing teeth was disabled recently. 

I am reverting back to a previous save before this happened to be safe.
