Mission Forbidden Vault invisible wall before second vault

In the Mission Forbidden Vault is a bug. I can't click on the "Enter the Vault of Souls". There is a invisible wall, my planewalker run against it, but can walk over the dark-golden line. The button is out of reach and a restart didn't fix it. And you need to go in to get ahead.

Very annoying itself and it was also a daily for Tolaria to do the mission.
