Impossible to return to my Age on my local Destiny

[TheScarFr]

• If I link to my "Trigon" Age, link back to Relto, and then link back to Trigon, the game freezes on image 1.
• I duplicated the "DoorRegion" object and the "DoorOpenClose" node tree,
  added the "Old" suffix to the old object and node tree,
  deleted the old object and node tree,
  saved the file and quitted Blender,
  opened the file, renamed the new object and node tree to remove the ".001" suffix,
  saved the file and exported,
  and I got the image 2 result;
• I did the same kind of fix and got image 3;
• idem > image 4;
• etc > images 5 to 11;
• idem > image 9 again;
• idem > image 10 again;
• idem > image 11 again;
• idem > image 9 again...

If I quit the game after the crash, relaunch the game and relink to Trigon, it works.
But if I then link back to Relto, and then link back to Trigon, I have the same issue.
Note: Of course, I corrected the node trees when required.

Here is a ZIP archive that contains the Blender file and the needed files to test Trigon (not the real Trigon, but a test/debug Trigon) on Destiny: TrigonTestDestiny-2025_01_09.zip

@Hoikas Do you think it's a Korman related issue, like I did though, or related to something else?
