So for http://battleofthebits.com/arena/Entry/takin+it+easy.json/26047/ I accidentally uploaded the wrong render (it was supposed to loop once before the fade). I've re-rendered it, but the problem is there isn't a button to reupload the MP3. There's just listen, donload, and get MP3. Why can't I reupload my render?

reuploading renders isn't permitted to prevent people from wiping out their own stuff. i did think there was a 24-hour reupload grace period, though. in any case you can get an admin to reupload it for you.

You can reupload within the entry period. Not sure about agrace period otherwise.

the thing is that this was an OHB so I couldn't even upload a render until after the entry period

duly noted
