I wish stuff like this wasn't done. Sites like anidb are even worse, splitting it into two different show entries, with the second cour listed as "Mobile Suit Gundam: The Witch From Mercury (2023)" ugh... It wreaks hell on my Plex server.
Agreed. It's needlessly convoluted at times. But over time you just learn to accept and deal with these quirks. However, I still get confused by them as well.
