Hello, everyone.
This is the development team.
A hotfix update has been released.
■ Fixes
Fixed an issue where the waiting time for obtaining chests was reset when changing stages (including changing the Plaguelands difficulty), so frequent stage changes could continuously prevent you from obtaining chests.
Fixed an issue where the waiting time for obtaining chests was always applied when relaunching the game, preventing you from obtaining chests during that time.
Changed the logic where a waiting time was always applied before you could obtain the next chest after obtaining one, as follows.
The system that unconditionally applied a waiting time after obtaining a chest no longer operates.
The concept of a 'minimum waiting time between chest acquisitions' is removed, leaving only a system based on the 'total amount of chests obtainable per given period of time'. (If you play long enough, with some luck you may even obtain chests consecutively.)
We sincerely apologize for any inconvenience this has caused.
Thank you.
