AION 2 Global has updated its Advanced Access known-issues list with a progression issue tied to the Duty tab.
NC says that if a character opens the Duty tab on the Map before reaching level 45, Duties may still be unavailable after reaching 45 and may not return until the following day. The current guidance is to avoid opening the Duty tab before level 45.
The same notice also lists an English-client title display issue: after obtaining Vanguard of Atreia, the title menu may display Shaper of Heavens instead.
Both items apply to AION 2 Global / Steam and should not be assumed to affect Korea or Taiwan.
