I have solved the Sundial puzzle but I was not awarded the Sunny Disposition achievement. Anyone else having this problem?

EDIT: Nevermind; It just popped up for me!

I also have finished the puzzle but do not have the achievement either....

Same issue here. :C

You both have the achievement

I finished it hours ago, but it still has yet to pop up on me. I'm just passing time now fighting the big boss.
