So I just completed the quest where you get the elder scroll from the Tower of Mzulft. I gave the transcribed lexicon back to Septimus and then went to the Throat of the World, where I was greeted by Parthurnaax. He said his usual line of "You have the Kel-the Elder Scroll-" blah blah blah and then I go to the Time-Wound to read the scroll and its not there. I went back to the Tower of Mzulft to look for it there but it wasn't there, and I went back to Septimus to see if he somehow had it but no luck. What the bonk?
