I just tried the formula a second ago and four attempts have given me 2 little statues, 1 wolf ring and 1 common stone. Mana statues also come out quite often if I use rank 6 materials.
So apparently the formula is still working fine. You used primary or junior?

*Edit: Unless they changed it and released a patch sometime between yesterday evening and now, cause I haven't switched my client off since then :3
