Seeing people run around as if they were mounted on FP ride

[Hrair]

This is a fun glitch I see usually a few times a day. A person being mounted on a windrider, completely oblivious themselves how they are appearing to the rest of the game

/reload and relogging can both fix this issue. Every vanilla server I've been on has this problem and it remains cosmetic. Doesn't change hitbox or anything along those lines since it's cosmetic.
