Currently experiencing a new bug due to the fix that was implemented:
On my fourth Character I had logged in after the patch directly but before the fix and had gotten but not completed any of the AC ticket quests.
Since the fix has been implemented any of my other Characters will get a Server Communication error No upon going to the Task/Quest menu, viewing the AC ticket quests and then leaving the that menu. My Fourth Character does not have the issue and has since completed 3/4 of the Tasks with the 10 Vet kills still pending.
The other Characters appear to have duplicate Tasks that do not update the completion status of the over all task. Currently if I look at the Vet Kill task I just mentioned Character 1 will show 0/10 as the status even as Character 4 has 1/10. The other characters are not contributing to the over all tasks seen when switching between characters. Since the other Characters have the Tasks pinned they will always crash currently on going into the Task/Quest menu. As the tasks have been cleared the tasks get cleared on other Characters but leaves me with several characters that I have to be very careful with in order to do anything in game.
