Minor updates to Guardian Tales may need to be downloaded outside of the scheduled to ensure a healthy playing experience and introduce new content such as the start of Guild Raid events or new stories.

However in the case that the same files are being downloaded every time you try to enter Guardian Tales or if a finished download restarts from the beginning repeatedly, these errors can be resolved by clearing your cache. 

Please note that switching servers or languages will require a download of additional resources even if your game is up to date.
