The site acts weird if you have ad blockers up. In my case it forwards me to the front page of the site immediately on finishing loading the file's page, and I just have to go back. I also used to regularly get the inexplicably broken links, but I haven't seen that for about four months... actually around the time I figured out the aforementioned issue, conveniently.
And I know the obvious solution would be to just disable the adblocker, but the fact that it makes the site act up also makes me a bit paranoid about doing so.
