There are gaps in my knowledge.
In this case it’s mainly because I don’t think Arc has a concrete answer either.
Like, there’s no timetable for anything. Arc would rather not make promises he can’t keep, and also it’s not that easy to make estimations.
But the way it looks, most if not all of the previous acts content is unusable in act 3. MC has the cursed arms and some girls have changed a bit. Can’t reuse assets.
So in a way, can’t say when things will normalise, or if that will even happen.
Maybe Arc has something more to say, but I think that’s the gist of it. No clue.
