TML message #4255 is not in the archive
This number lies among the messages of bundle 350, whose table of contents does not list it, so the administrator appears to have skipped it.
Message numbers can be missing because a message was never sent to the list, because it was lost before the archive was made, or for reasons that the surviving files do not explain. Read about the gaps in the archive. If you have a copy of this message, please get in touch.
