Script classname [script_name] not found.

[Lunarovich]

I'm having an issue when I try to execute

 

local entity = self.entity:Copy()

 

I get an error "Script classname sin not found." The self.entity in question has a script named Sin.lua attached.

 

Any ideas?

 

EDIT

After renaming and reattaching the script file, everything seems to work for now... Does it have to do with the fact that I've edited it in the external editor?
