Hi Luke, Thanks for flagging this — you were right, and it was on our end. A bug was miscounting your uploads and cutting you off at 11 clips even though the real limit is higher. It's fixed now. I've reopened your submission so you can pick up right where you left off — just add the rest of your clips and submit again. You shouldn't hit that wall this time, and if you want to include more clips than before, go for it. If anything acts up at all, reply here and I'll jump on it right away. Thanks for your patience — and for helping us catch this.
