Stuck at Strange Tremors

[Walleampe]

Greetings,

After i talked with eiden the strange tremors do appear. So i go to investigate that
after i found the faceless at the west wing talked to them nothing is happen.
(there is also nothing happen if i go after talking)

So i think this must be a bug but i hope someone will know how to handle this.

the only option is reveal eiden the faceless invasion but as i remember
i could go north after talking to the faceless and jump down
but this is no longer a option for me because nothing
is happen. Ah damn...

Nevermind.

but i remember there was another way.
