BUG: https://mangadex.org/manga sent me to a non existent manga. :rejected:

The manga number was #38200 in case that matters.

The cache for the random manga gets updated once a day, so I'm guessing you coincidentally happened to hit a manga that was deleted earlier during that day. Technically a "bug", sure, but I don't think it's important enough to address. It doesn't cause any actual harm.
