Ok, here's the CGs I'm still missing:
"Aoba's Tumbling at the Marketplace" - will be fixed next patch
"Saved by Maximus" - Is this the scene before the Treant fight? If so, pretty much everyone should have that.
"Cronus and Maximus at the Opening Ceremony" - Everyone should definitely have this one. Like, it's a mandatory event.
"Aoba's Onigiri" - Yeah, don't know what scene this is, so I probably legitimately don't have it.
EDIT: Also missing "Gimdin Taking a Break" which I have definitely seen.
