It is currently possible to get trapped within the Provenance / Walk of Echoes area at the end of VW. If you have not progressed far enough in the WoTG missions, which share the same part of Walk of Echoes as the Provenance warp, the Conflux to exit the zone does not respond to you, leaving you no way to exit besides magic/items.
We had two LS members (myself included) who have not finished WoTG be unable to exit, while two LS members who have finished WoTG were able to use the conflux to exit no problem.
LS members who were not finished WoTG received the message "A mysterious column of floating stones rotate before you"
LS members who had finished WoTG received the message "Proceed to Witchfire Glen" before being transported.
