So only half or so of Episode 4 Story released so far?

As the thread title says. I've completed it up to the fourth chapter I believe and it's telling me to wait for the next episode. From the JP wiki (and my experience running through Episode 4 on JP) I don't think this is where I remember it ending. I can't be going crazy right? Is it being released throughout the next couple of weeks or something? Not that I'm chomping at the bit for the rest of the story, but I do want those titles.

More will come when the relevant raid UQs get released.
