Shout out to @[email protected] for letting me know in the thread that rikka made for the episode. I was able to confirm that AniList updated the api for this episode to have the proper airing time (though currently episode 16 also has the same airing time in the api). I also muddled my way through the sql statements on a mobile ssh client to fix up rikka's database and remove that episode.
I think the next modules I will be making for rikka are some helper functions to help me from ever having to do sql from my phone ever again.
