Can't get enemy hero z position

One of the ways I’m trying to detect jump in Dungeon Arena is based on the z value. Their position co-ordinates store z but when I try to check it, it fails. If I ever try to say it, that fails with the error “say what?”. If I say the entire .pos co-ordinate, I get the z position in the array.

All right, all right, I’ll add z the Vector’s API; should go live with the next deploy.
