I played Wagstaff without goggles and gathered from a dung ball and the crash happened. But don't I think it was the issue. Sorry, I am not familiar with codes. Crash screen indicates an error in the hoverer.lua. Maybe my mouse was hovering over an object and you know about Wagstaff's nearsight and random object names.
Read posted crash screen. I was playing Wagstaff in a Hamlet world.
