I was about to create a thread about this. There is a significant gap between chapters 244 and 245. One is discussing and hyping a duel between male students, the next chapter then starts with the word "However, " and then proceeds to talk about two other girls insisting on joining the ground forces in a war. In the context of the story these are quite obviously disjointed. It is evident that there is a gap in the storyline here, which indicates missing chapters.
The next chapter then takes another jump in the story which again indicates missing chapters. Is there a correction to this in the works?
