I will just keep reporting stuff I bump into: just to help iron out the bugs... :-)
In the log.txt I saw the following errors:
Error 1
Failed to open D:\X-Plane 10.45 beta//Custom Scenery/OpenSceneryX/objects/aircraft/jets/corporate/citation_x/unlit/object.obj: the file cannot be opened.
X-Life Object load error: D:\X-Plane 10.45 beta\/Custom Scenery/OpenSceneryX/objects/aircraft/jets/corporate/citation_x/unlit/object.obj
Failed to open D:\X-Plane 10.45 beta//Custom Scenery/OpenSceneryX/objects/aircraft/jets/corporate/citation_x/lit/object.obj: the file cannot be opened.
X-Life Object load error: D:\X-Plane 10.45 beta\/Custom Scenery/OpenSceneryX/objects/aircraft/jets/corporate/citation_x/lit/object.obj
I checked: there are no objects in the lit and unlit folder -> the object is directly placed in the citation folder. From the library.txt:
EXPORT opensceneryx/objects/aircraft/jets/corporate/citation_x.obj objects/aircraft/jets/corporate/citation_x/object.obj
Error 2
Failed to open D:\X-Plane 10.45 beta//Custom Scenery/OpenSceneryX/objects/aircraft/jets/heavy/a320/frontier/object.obj: the file cannot be opened.
X-Life Object load error: D:\X-Plane 10.45 beta\/Custom Scenery/OpenSceneryX/objects/aircraft/jets/heavy/a320/frontier/object.obj
Here it is the otherway around: the obj files are in sub folders. From library.txt:
EXPORT opensceneryx/objects/aircraft/jets/heavy/a320/frontier/cougar.obj objects/aircraft/jets/heavy/a320/frontier/cougar/object.obj
