I just learned today that there is a bug in Beast Boxing v1.2 that will prevent accurate syncing of the “Mad Skills” achievement to Game Center for winning Beast Boxing 3D on Hardcore difficulty mode. When a fix goes in, I will do my best to ensure that profiles who have this achievement locally will sync properly to Game Center without having to re-beat the game. It’s hard enough the first time! Thanks to Mark Simpson for reporting the problem.
UPDATE – This bug has been fixed! The free update is now available for download on the App Store.
