Doesn't always happen, but I don't know why it sometimes happens or how to replicate. I was using a lot of client mods so that may affect it. Sometimes I would go to open Woby, and the entire game would shut down when I open Woby. Happened twice within an hour. Woby had a few things inside like chester's eyebone. Seemed to happen both times while Woby was running away mid open.
play walter and open woby.
