About current Grand Conquests event: (Notification)
We hope that you continue to enjoy Fire Emblem Heroes!
Dialogue scenes for Hector, Eliwood and Lyn do not appear in the currently-running Grand Conquests event due to a mistaken setting.
We plan to release updated data at around that fixes this. If you download the data and enter Grand Conquests again, you should be able to view the missing scenes.
