So I just finished feeding my pets 100 carved pumpkins and even my achievement page says I have done so on the counter, but the achievement won't unlock. Is there a specific place I have to go to get this achievement to unlock or is it just bugged?

I just checked your achievements; you have it already. c: It just sometimes takes a minute to update. Maybe try a hard refresh if it doesn't show up soon?

Oh wow, I feel silly. It wasn't doing anything for like, 5-10 minutes and I never got the achievement pop-up, so I was just like B| why you no work, achievement. Thanks so much!
