From the people who reported it in this thread 7 months ago, they were using Windows 7 - if I remember correctly. Is that the OS you use?
If it is a compatibility issue with Windows 7, Unity, and the coding in the game - It is highly doubtful that they will attempt to troubleshoot because of Windows 7. So few people use Windows 7, they have more priorities than to attempt compatibility.
That said, the animations you seek are behind the spoiler at the bottom of my message that I posted 7 months ago.
