In the most recent patch notes you claimed that Titus Valerius will now follow players normally throughout the Rahni'Za Library, but this is false. My girlfriend and I both tried to do the quest on the PS4 N/A server and the moment we interact with the final set of books he says "that's the one" or "let me look at that" or something like that, but the quest doesn't continue, he just vanishes in thin air leaving us stuck. We also witnessed other players running in and out of the library trying to see if they could find some way through the quest because it's bugged for all of them as well. Why this was put in the patch notes as being fixed when it's clearly not is beyond me. I'm dead stuck in the middle of Craglorn's questline with no possible way to finish.
For the Covenant!
