Already reported this bug, wanted to throw it up here for some feedback. BTW Turbine, your in game ticket submission is broken YET AGAIN! Not cool.
I can no longer talk to Vorace <Draconic Scholar> in Reavers Reach. This life after TRing I did all flagging quests, got essences and did SOS. Took the draconic runes to Vorace to trade in for an Eberron essence because I didn't have another on me to run SOS again and turned in my 50 draconic runes. He took the runes but did not give me the essence, I do not care if I get these back. The bigger part of the bug consists of Vorace no longer speaking to me. I have tried everything from logging out, redoing SOS, to waiting over a week now. No change.

Step 1> Flag for Stealer of Souls

Step 6> Notice you no longer have the Draconic Runes

You are no longer able to trade in Draconic Runes.
