Thanks for the fixes.
I've just checked 100% save gallery, and to my surprise, the problems that I've listed before are all different from what I imagined.
Basically, all the events that were previously locked for me on my save files are the ones that I've seen already.
Despite seeing the events/nightmares, they still weren't unlocked in the gallery. In other words, it's not that the events/nightmares didn't appear in the previous versions, it's that they didn't unlock in the gallery and weren't accounted for in stats screen.
So technically speaking, I think players are able to see all the content legitimately, it's just that it might be not unlocked in the gallery for easy re-viewing.
P.S: The locked stuff for me was "Here with us... Forever" despite answering both "yes" and "no" in the ending. Also the "Other Stuff" wasn't open, which is mostly BG. Sooooo... I think the bugs aren't that much of a big deal at all!
Apologies for pestering you yet again with the abovementioned and thank you kindly for your hard work! I really did enjoy the game. ^v^
