I think it is the second time i saw that. Each time, it was in the object editor, in a dummy caster data. Instead of the crap i wrote in model file data and don't have model ingame, the value is The_evil_is_just_behind_you.mdl...
Don't know, but I remember a LONG TIME AGO all my Object Editor stuff was edited randomly and I had to default everything that I tried to use if this is related in anyway.
