Custom object not showing up in scenery list after last SDK update

I have ways managed to import objects into the sim without problems using the powershell method of building the package. Now it seems this does not work anymore. My objects are no where to be found in the scenery list.
I never had this problem before. My workroutine has not change at all. For some reason this method does not work anymore.

You can see here that the package was build without errors like it should:

Still the object don’t show up in the sim after having placed the package in the community folder… what gives? Any ideas?
