A lot of Japanese players met this bug on Japanese Pure.
1, Download the packs of Japanese version, included...
Gamma pack 1~32, Play Exostra Run at any modes
Delta pack 1, 2
Classic Pack 1~4
3, After playing, when returning to the menu, the game completely freezes!
(In tournament mode, it may happen when moving to Exostra Run.)
If game does not freeze, add wire05 and coke packs then try again.
I heard this bug was fixed in EU version...
