It messed nothing. When he got 2 of the teachers almost done he decided, based on people opinion on the streams if I'm not mistaken, to just go all the way and make the 4 in one release, taking the same time as it would have taken with 2 separate releases. The only thing that messed the schedule was the patreon incest thing.
Poeple just get impatient when the release is close. It's always the same shit. I mean, c'mon, one can not calculate a precise date for these things, you just know you are on the final steps and that it will come out soon. And yes one week is soon when you come from a 4 month production lenght.
Anyways, I'm glad to hear about the Roxxy update. I like how the new story arcs are getting "denser", like there's more things happening story-wise compared to the older arcs.
