Yugioh challenge

I've been tried to submit for around half an hour before deadline hit as I'd been having rendering problems with the model prior. I've had the error, 'there was a problem in our system' on the submission page for all that time. I imagine now I can't submit, and I'm more upset than frustrated at this point. Using Stud.io is a challenge for me on the best of days to say the least, but I tried regardless. I don't think I would have gotten far with my design, but still, incredibly disheartening...
