App uploaded to TestFlight w/Transporter but now gone

After uploading an iOS app for peer testing, users got 'invitation expired' errors. The next day I'm attempting to fix this problem. The uploaded app no longer appears anywhere in the app's TestFlight pages. What happened? Ho do I fix it? I can't re-upload, of course I get 'that version already uploaded'.
