Some messages got false media

[Jimmm]

20MB json file, converted to html. The false media is in json and in html as well. In html it is ok from the middle of the second page. The dump has 18 html pages in total. I see that the first media in that group was a video and it was not downloaded at all, so that message became a picture from the massage below and this shift persist across 1.5 html pages. I didn't check all 18 pages, but the last ones are ok.
