I purchased an Angelic Chibi Rainbow Sticker and used the Self Sticking Service, but the Achievement page didn't update and I didn't recieve my achievement. Is it bugged??

edit: it is not bugged, you have to go to the sticker album! xD

Have you been to your sticker album (Lazy Link)? I just bought the sticker and self-stuck it, and the achievement was awarded as soon as I went to the album :)

oooooooh, I didn't know you had to go there. I thought I was only supposed to go to the achievement page, haha! Oh I'm so sorry!! the achievement is NOT bugged!
