When I download the most recent Trainer for BL2 (18.104.22.1681067 (10.22.2013)), there seems to be an issue. The trainer contained within the .zip file is version 22.214.171.124171, not the most current release.
I have tried downloading the file multiple times, even using different browsers, but still cannot obtain the most recent version. Is the download link just pointing to the wrong trailer? Link
