Soooo... I've gotten all my kisses. But it hasn't given me my Full of Love achievement. Anything further I need to do to gather it up? -.-

You'll need to submit a ticket and have an admin add it manually. This has been happening to a lot of other people, apparently (myself included) XD

Send a ticket, that's what I had to do. Can be found by clicking "Contact Us" at the bottom of the page.

Figured as much. xD Thanks a bunch.
