Issue with a data update not being applied correctly[Addendum]
Due to a data update issue, we were unable to start the Gala Dragalia summon event, the Imperial Onslaught half-stamina event and the Light-Attuned Adventurer Upgrade event on Jan 9 22:00, 2019(PT) as planned.
This issue was fixed in another data updated applied on Jan 9 22:10, 2019(PT).
[Addendum Jan 9 23:40, 2019(PT)]
While the above issue was happening, we noticed that the "Stamina 1/2" sticker was not displayed on the fire, wind, and shadow-attuned Imperial Onslaught event banners.
After further investigation, we have confirmed that while the sticker was not displayed, the consumed stamina when playing those quests after Jan 9 22:00, 2019(PT) was indeed halved.
Thank you for your understanding.
