I have strange problem, I wanted to try to take away my belongings from default.xml files that I created by adding my items, or tried to take away should be simple:
Load the file with default.xml AutogenEditor, I view these objects, select my 4 lights and Remove do, I save with the same name.
The file is generated but loses other items that I have not removed, in fact you no longer see two objects added previously.
Loading in annotator recognize them as library objects 2 remaining ... but not in P3D.
The removed items are part of 4 different classes from those always remained mine.
I tried to remove by hand default.xml objects by editing the file but it does not work.
There is a special procedure to remove objects?
