Well, not exactly removed. I renamed it to show that it's the version uploaded in 2008. Just so the "original" version is still available for whatever reasons people might have. Because that's what archives do. Archive things.
Usually I don't do things like this, but this bit is actually a good argument against the standard procedures.
That version was uploaded to the Knytt Stories level archive without my authorisation and even though I have made it clear in the past that I am not okay with that (among other reasons, precisely for the unavoidable versioning issues that result).
So, the original filename is available again, if you wish to upload the final version.
