Thanks for the heads up! FWIW: It looks like Shinobu managed to post exactly one Bungo thread: https://ani.social/post/36938. Yes, "Bungo". That's the official English localization that got chosen even though the fan community obviously prefers the Hepburn romanization.

In any case... the ominous "Episode 51" from the linked thread's title seems to suggest that something janky went down with the handling of episode numbers. Under the hood, I imagine something like this is going on: "the prior episode was episode 51 and MAL says that we're not at episode 52 yet, so there's nothing to post!". I do see that there are upstream changes to the summer season config which include an offset for the bungo crunchyroll source, so I'll start by pulling that in and seeing if it has any effect on the problem. If not, then it might take a little while longer as I try to figure out a good way to manually unstuck bungo's episode counter.
