On a private forum, I have a topic created by a WordPress user (A) with Administrator privs and forum Keymaster privs, and a WordPress user (B) with Subscriber privs and forum Participant privs.

If User B clicks on a topic created by User A, B does not see the topic but gets a 404 error.

However, user A can click on and view topics created by user B.

Specifically, if user B is changed in privs to a KeyMaster then they can view the topic posted by User A. When they are switched back to Participant, they get the error.
