Creating a quick config in description.ext

class testClass {
	class testSubClass {
		myProperty = 1;
	};
	class otherTestSubClass {
		myOtherProperty = 2;
		something = 3;
	};
};
class otherTestClass: testClass {
	delete testSubClass;
	class otherTestSubClass: otherTestSubClass {
		delete myOtherProperty;
	};
};

and then checking in config viewer otherTestClass >> testSubClass still exists, but is empty.

In addition to this, the following error message is thrown in RPT: 14:04:47 Warning Message: class 'e:\nextcloud\arma\missions\tmf_dev.vr\description.ext/otherTestClass/testSubClass/' is not defined
