Currently all units have a bug when they have just been created. Unlike horses and units with capes most of them don't have animated props and are fine.
That's because when initialized the m_AnimationID field is an empty string which prevents the props from syncing.
Here is an example video: https://wildfiregames.com/forum/uploads/monthly_2021_03/1821934873_2021-03-2513-32-47.mp4.1925c379d26d2230bebf684a3fdb850c.mp4
This patch fixes that.
