[SPOILER]Skipped main scenario ending cutscenes. Now they're missing from my inn log.
On my first character, while running Praetorium, I got matched up via Duty Finder with a speedrunning group that kept leaving me behind and threatening to kick anyone who watched cutscenes. Not wanting to rock the boat, I went along with it and dutifully skipped every cutscene as they appeared. When we got to the end, after defeating Ultima Weapon and Lahabrea, I skipped the ending cutscene as well figuring I had already skipped everything else and would just watch everything together in the inn later.
After watching [what I thought was] all the Praetorium and Main Scenario cutscenes at the inn and turning the final story quest in, Minfilia mentioned a primal roar being heard during a celebration. I didn't remember any roar or celebration from the cutscenes I had watch and thought it was odd, but didn't think much of it and went on with my remaining endgame quests.
Now today, on an alt, I also ran Praetorium and wrapped up my story quest. This time, I didn't skip the final cutscene and let it all play out. To my surprise, there were three additional cutscenes I hadn't seen before after saving Thancred and escaping the installation, showing a celebration in Mor Dhona, announcing the end of the Seventh Umbral Era, the credits rolling and what was presumably Bahamut re-awakening. I went to the inn after and noticed that there were 4/4 cutscenes listed under "The Ultimate Weapon" entry.
Going back to my first character, I only have 1/1 cutscenes listed--the first one of the four, showing you racing ahead of the exploding fortress with Thancred--under that entry. I thought perhaps by running Praetorium again the last 3 would play, but it just dumps me back out into the overworld when I click on the exit portal and the main scenario ending cutscenes don't play.
