Score deleted on its own; still shows up in my scores
This morning I uploaded a score. It's worth noting that the score is 2 hours long - an extremely large score. I uploaded it with score audio and waited all day for the score to finish processing. I checked it half an hour ago, and it gave me a page not found. Which is weird, since it still shows up in my scores list (see screenshot). Yet it still shows that I have 4 out of 5 scores uploaded (if you look at the top of said screenshot). I was wondering if there could be some way to recover my score, or if I'll have to upload it in a different way.

None of my other large scores have given me problems before, so I'm worried that uploading this one will be impossible. Also, why does it take centuries for the score to process? I already uploaded it with audio.
