Cannot save project after removing subproject

[jpsim]

Subprojects in Xcode look like PBXFileReferences to Xcodeproj. So they should be removable in the same way as a regular file, by calling remove_from_project.

Unfortunately, this doesn't work.

project = Xcodeproj::Project.open('MyProject.xcodeproj')

project.objects.each do |object|
    if object.respond_to?(:name) && object.name == "MySubProject.xcodeproj"
        puts object.path # => object is there and has the correct path
        object.remove_from_project
    end
end

project.save

Output:

../../MySubProject.xcodeproj

Doing the same thing with a regular file saves without a hitch. Any thoughts?
