Gust has released a patch for Atelier Ayehsa. In addition to some bug fixes, the patch readies the game for future download content. Gust said that it would share specifics on future DLC plans in a later announcement.
The bug fix part of the patch addresses such issues as the PS3 resetting after a particular event once Rinka becomes a member of your party and an infinite loop when Rinka uses her checkmate move in battle.
For those of you keeping score at home, this patch takes the game to version 1.01.
