It happens. Last year, I almost uploaded my entry right at the ending because I was testing something.
I uploaded the correct version seconds before the deadline hit. It was like a movie! ^_^;
That entry has since been delisted for a few reasons, but I'm going to repurpose it next year.
Finding out about something like this sucks and I certainly don't want to be the bearer of bad news,
but at least there's a little sunlight in this cloudy situation!
Take solace that there's enough content here for players to grab onto.
I'm certain there are entries that don't plain work or haven't had anything uploaded at all. Oof.
Then there might be entries that do work but carry the uploader's pet viruses with them.
Ranking on the nightmare scale, this particular case isn't so bad! d(^^)
