Rook has one eye that points inwards

This has happened on all Rook's I've made so far. Their right eye (on the left as we look at them) always points inwards, so only the left eye (on the right as we look at them) looks directly forwards. Presumably a problem with the model and eye tracking? I've noticed it in other people's screenshots of their Rooks too. I've only made elves so far, I don't know if it's restricted to only their models.
