Scale and alignment of attached parts lost on 3mf reload

[bartrv]

Version

Operating system type + version

Windows 10 x64

3D printer brand / version

MK3S+MMU2s

Behavior

When using "Add Part...-> Load" on an object scaled in slicer the default behavior is to translate the imported stl part to the position, scale and orientation of the parent object it is added to. Which is great. If there is an update to an attached part, the stl can be overwritten and "Reload(ed) from disk", the update swaps in seamlessly.

• the Problem:
  If the 3mf file is closed and reopened (both by closing/re-launching slic3r AND by opening a different 3mf file and then re-opening the original file) any Added Part that is "Reload(ed) from disk" looses its alignment. The x, y , scale, and orientation are maintained, but the 'z' alignment is lost and the reloaded stl appears floating above the object it is attached to.

Is this a new feature request?
Nope
