I marked a group as excluded in my feature definition, so why isn't the exclusion applied?

When doing feature comparisons, point and vector features are considered to be in a different class from group features. For example, a point acceptor will not match a group acceptor. If the acceptor you exclude is defined as a group, the point acceptor will not be excluded even if matches a point in the group. However, if you redefine (or duplicate and define the copy of) your point acceptor as a group with one atom, the match will succeed and the acceptor will be excluded. A vector feature will, however, match an excluded point feature because they are in the same class.
