It seems that it is stuck in a loop, trying to make my package and rejecting it. Every minute or so it adds two more 'rejected' log links to the page here:

If it helps anyone figure out the issue, I first gave it a new version while forgetting to increment the version number in the relevant debian packaging files, and then accidentally uploaded the same exact set of files again instead of the correct version-incremented ones because I was inattentive and clicked the wrong files in the file selection prompt.
