Hidden Forum / Access Masks problem

[sydeburnz]

After upgrading to 3.5.1 from 3.0.7 I have encountered a slight problem with a secret forum I have created. Basically, only the admins have access to it through regular permissions, and then some other users have access to it as well. I have granted them access by going into the user page from the admincp and the used the Edit Forum Permissions (Access Masks) area. In this area you can override (yes, no, default). The problem is after I have upgraded, it is making me go into every single users page, and if i resave it works fine. I was wondering if there was a magic button somewhere I could push instead of having to remember everyone i gave access to and edit each member permission.
