incorrectly handling a non-zero offset in the child

	if (1 == cData.count) {
	changed = true;
	// erase child and replace with gchild
	// delete the child (only 1 child) and replace with granchildren
	std::vector<Type> gchildren = child.children();
	type.children() = gchildren;
	}

If the child has a non-zero offset, it needs to be added into the parent before its removed.
