A couple bugs:
Doing a run where I confess to Narberal. After we get back from the fight with Clementine, the game keeps saying that I have a new event in Ainz' Chambers despite no such thing popping up. Also, Kyouhukou's scene doesn't update on the gallery.
Secondly:
Amusingly enough, because of an earlier build save I am able to propose to the vampire girl despite already being engaged to Albedo, and the Marriage Announcement with Albedo plays up naturally. But then scenes after that act like the vampire girl is my only wife and none of the new events with Albedo ever happen.
Edit: I just realized Narberal's scenes don't pop up in the Gallery either... Maybe I should just start a new game to not interfere with old saves and avoid any potential glitches. Flying through all the scenes holding the skip button hardly takes time either.
They're not bugs, some gallery scenes unlock only after you view both the outcomes of "Cum inside" and "Cum outside".
As for the vampire (I presume Rosalyn?) that could be a bug, so I'll check that out, ty.
The game warning of a new event in Momonga's chambers is something I am aware of, but unfortunately I have yet to find the cause, I'll look in the part of the events you were in, perhaps it'll help me figure out why.
-edit-
I checked the Rosalyn's event and it does check whether you have a wife or not... I may have forgotten to put a check in past releases and fixed it later on, hence why you could get both, but as of R16 it should not happen.
-edit 2-
I might have fixed the new event issue, but it is hard to tell since I do not have a save with that problem.
At some point I'll just replay the game over from the beginning to hunt for those minor issues.
