Daily login reward missing
Did you accept the chest after interacting with the Daily Task option window? Did you change characters before accepting the chest? The chest is soul-bound to whichever character you log in with, or is active when reset occurs.
Good luck.
Login to character
Click chest and accept the dailies window thing
see the daily reward appear in the scrolling loot window thing
Nothing appears in inventory.
You can try a -repair of the client, in case of corrupted file(s).
You can contact the CS Team for assistance.
Both can be found: Top of Page – Support – Search (Repair) or Submit a Request
Good luck.
