Due to a recently discovered potential exploit that involves the temporary stage progress saves in Guild Wars and Raid Bosses, they have now been temporarily disabled. Instead, the refresh time will reset back to 00:00:00 if your app crashes during middle of these fights so you can restart immediately. Please note intentional abusing this temporary reset fix will be considered cheating and we will be closely monitoring players who repetitively restarts incomplete battles.
The save point feature will be re-enabled for Guild Wars and Raid battles once the App Update including the proper fix have been approved and released. Sorry for any inconveniences this temporary change will cause.
