So, I go to my achievements page, and this is what it says, under the Vesnali category:

click~

44/25? o.O Is it glitched?

Looks like a glitch yeah. You can send a ticket I think, and see if they fix it.

The last Achievements were released trough the end of Vesnali and you had to buy an item from the shop again, find a flower again and send a flower to someone again to get them. :(

: Oh, I see. So they're basically stuck like that till next year?

Unfortunately, yes :( I believe even if you buy an item now it doesn't count anymore because Vesnali is over. :(

Oh. Darn. Thanks though! :D
