Short description of error

Exact steps for others to reproduce the error
See the attached Blend file, export the 'Export' collection as an FBX. Try with Tail bones on and off.

I don't know if I get all the steps correctly.
Is it missing any steps to reproduce the bug?

Sorry, You need to import the exported FBX back into Blender to see the results.

I don't understand what you meant by "Try with Tail bones on and off" (maybe because this is not my area).

I need to reproduce the problem to assign it to the right person.
But this report does not have a precise description of the issue with precise steps to reproduce it.

It's not you it's my hurried reporting!

I meant with 'Add Leaf Bones' on or off. The image in the description shows the Original file, then two FBX files (Leaf bones on and off) imported in fresh blender scenes.

This is the FBX setting I was referring to.

Thanks again and sorry for the confusion.

Tail bones are precisely there to fix those tail bones issues (FBX does not use the same "bone" model as Blender, it’s closer to the 'Joint' concept of Maya e.g., conversion from one model to the other is not always super-simple…).

Thanks for the report, but afaik that is known limitation, not a bug.
