Last week I bought Secrets of the Obscure. It tells me to "Read the mail from Caithe". I have not received any mail from Caithe and in my Home instance there is nothing to progress either. Am I overlooking something? I have sent a bug report but nothing changed. I have tried ending the Quest but apparently I can only continue it where i quit the quest leaving me at the same spot, with the same issue of no Mail from Caithe.
Any tips?
