I was in the second level of expedition fighting a unique mob that was channeling some kind of a 'frost ray' skill.
I was channeling Solarfall and had a Livor Mortis active,
The game closed without any OS notification, checked event viewere and still nothing.
Considering this it seemed like a handled exception, checked %appdata% found no wolcen logs.
If needed I can provide the logs if I'm provided with their location.

Thank you,
Edis
