The animation of a frightened armadillo looks like two armadillos overlapping if installing the First-person Model and Sodium together.

Not sure what Firstperson is supposed to have to do with this?

I was so ready to call bullshit on this, but actually can reproduce it.. What the heck. Even seems to be correct that it only happens in combination with Sodium. This is certainly a first(extra stuff rendering on other entities. so far it always has been stuff not rendering).
