Could the length of a Minecraft creepypasta on a wiki cause a 422 error during download?

Yes, the length of the creepypasta could potentially contribute to a 422 error. If the wiki or the underlying server has limitations on the size of data it can process in a single request, a very long creepypasta might exceed this limit, leading to the error. This is more likely if the data isn't being transmitted efficiently (e.g., not compressed).
