Disregard my previous post. It DOES appear to be whitelisted and tracking properly. For some reason it wasn't before. Most likely I had something else active that was disabling stat tracking.
EDIT: Very strange, I made a post before this and it said that I needed moderator approval, yet this post went through immediately. Anyway, my *actual* first post stated that the mutator was disabling stat tracking. I was wrong, and the mutator is fine.
New user, so I'm a little confused as to why that post required mod approval while this one didn't. Oh well. Hi forums!
