A patch for A Crack in Time is expected shortly to correct a issue in the game. According to James Stevenson of Insomniac Games at the NeoGAF forum, the update will fix a bug that will cause a challenge mode game in progress to suddenly revert into a regular game. No exact release date for the patch was given, however. The game was released in North America in late October and recently came out in Europe earlier this month.
James Stevenson on NeoGAF:
This is the weird challenge mode bug that morphs your non-challenge mode game with a challenge mode.
It happens when you cancel out of the save for challenge mode as a way of saying no.
Patch forthcoming.
