Thanks for the report. This has happened as the mod failed an upload check, due to a new upload checker that I put in place. It's not that anything is really wrong with the upload checker, but when people don't use a recent editor test patch to export their mod, it's possible for this issue to come up due to issues in their old version of the editor.
Then, when that does happen, the website doesn't really do the right thing, as you noticed.
I've notified Victor to see what he can do on his side, and also I've reinstated the original upload checker so this doesn't keep happening right now.
I will now notify the uploaders of a few mods that have gone wrong in this way since yesterday.
