Bumping this thread up because this is just something that kinda popped in my head today:
Some of you speculated that episode 12 was missing just because it didn't leak.
Well, as ridiculous as I do think it sounds since it's just mere speculation, I think it could also be possible whoever leaked the episodes possibly used the already digitized copies of the episodes from a computer and just forgot to take that one
Not that it really matters but I felt like I might as well throw in some two cents about it.
