Images such as this (SFW https://derpibooru.org/images/3386766) are no longer downloading, or copying any tags to the clipboard. Other images work fine. The problem seems to be the new Ai-related tags: ai content, ai generated, generator:, prompter:, as boorutagparser obviously has no knowledge of these. I'm unsure of Parser's ability to handle novel arbitrary tags or namespaces, but some or all of these tags seem to be the determining factor in why certain images are failing.
