Stager rotation animation rotating items within a selected group

[stevestrauch]

Hello community,

I have several appliance models that I need to record a 360º rotation, all have been successful.  My last 2 are demonstrating some odd behavior:  I've placed all the items for the object I need to rotate into one folder (which I've done for all the previous objects).  I've selected the folder to rotate, but when I play the rotation, only part of the object rotates, not the whole shape.  Weird...  My other model shows a different, but equally puzzling result: The entire model rotates, but one part of the model rotates at a different pace, like slower or something.  They all return to their correct position, but again, weird... 

If anyone has experianced this, let me know if there's somethinhg I'm doing wrong, or if this is a bug

Did you group them all?

@Ares Hovhannesyan pardon my late response, but yes, they are all grouped.

Can you share file for testing? Thanks
