I've been experiencing the same issue, hopefully it will be addressed soon.
Correct, she never appears outside the inn. I don't know if it makes a difference, but Aewen's story is the first one I've completed, so I don't know if I should complete it after others.
I may have encountered a bug. After completing Aewen's plot, I never encounter the trigger for Gobboe. Is there any way to fix this?
