Thanks for letting us know! We checked into the bug and it appears the fix implemented in 1.4.7 fixes Septima in most situations, but not all. Some additional work has been done on this bug and will be implemented in a future patch. We don't currently have an ETA on when this fix will hit the live server.
For now, you may exit the Far Shores by logging off and waiting for about 10 minutes. Returning to attempt the quest again should prove successful in most instances. Thanks for your patience and the additional reports, we really appreciate it!
