Bad formdata when submitting to October Challenge

I apologize if I’m missing something simple again. I’ve done probably three or four LDJam’s and never run into this error.

Here is a screenshot of what I submitted. All of the .png files are within the specified size range. Is there an admin that can maybe look at a log file to see why this error happened? Thanks for your help.

Try unchecking anonymous feedback, it could be disabled on this october challenge.

Thanks for the suggestion. I just tried that but still got the same result.

Pov gave me the solution to this on Twitter. I submitted the game with only one pic and then added more in an edit. For some reason on of my .png files still would not upload, so I’m guessing that one was the culprit.
