I detected I have some “ghost” objects in a file: I appended a group from that file into an other file, and there were suddenly objects visible that I din’t expect to be there in this group.
Checking in the original file I see that these objects are not shown in 3D view and in Outliner View - All Scenes. BUT they are shown in Outliner View - “Blender File”. But I cannot really select them there, and I cannot delete them.
How can that happen? How could I find such “ghost” objects, and how could I delete them?
Thanks for any help.
