I think you should have only seen this when Aeventexhumed was a character -- it's nothing to worry about, just letting you know a factor conversion had to happen (which is almost surely what you wanted). If you see this when Aeventexhumed is a factor already, that's somewhat surprising. What does str(data.to.analyze) show you?
