We found an issue with the All Star Player achievement and made a hotfix. The problem was that this [b]Achievement[/b] was checked ONLY if the player had 60 stars. (20 levels x 3 stars). But, because some of the users are also playing the bonus levels, you can achieve more than 60 stars so no data is sent to Stem. Now, we make a check and this should be fixed. Thanks again, Raul from RVL Games
