Blender Object loses Alignment during Rotation (Only During Render) I have a blender object which animates / rotates along the z axis just fine in the viewport:

However, when I render it in either Eevee or Cycles, the object (hilariously) loses alignment and breaks apart:

Can anyone help me figure out what's the cause of this really strange behaviour at render time?
Edit: deleted all my rendering configs.  Issue was caused by original object overlapping with my Collection Instance and showing up on render. I had to hide the original object in order to make it work on render.
