Multihoster and mirror handling: Do not (always) trust final filename
In this case, host plugins are all returning correct filenames.
However once the user starts the downloads which will be done via real-debrid, files will get slightly different filenames --> Mirror handling fails and files may get downloaded twice.
See example URLs and log.
