After I got a new computer more than a year ago, I forgot to back up my Steam stuff. Rookie mistake, I know. Thing is, I can't update a specific machine I've made, and to add insult to injury, I'd disabled the [redistributable] tag. So I deleted it off the Workshop to see if I could reupload it again.

Big fʊcking mistake. Still has that damn "prohibited" thing stuck on it.
Copying the block data in the .mcbd file to another machine? Didn't work.
Removing the Workshop ID and changing tags in the file? Nope.
Well, on the bright side, it means that you effectively can't tamper with others' files to reupload them if unauthorized.

In the meantime, though, if you want it...
