@askvortsov it doesn't look like anyone has reported this issue yet, but, if you assign a nested or a secondary tag to a primary tag that group restricted, the title of the discussion still shows in the "Last Discussion" widget. If you click on the title of that discussion, it'll notify you that the resource cannot be located (this is the expected outcome).
In my case, "[DRAFT] Rules & Guidelines" is assigned to a primary tag that is group restricted, but I have a secondary tag labelled "Draft" that is accessible to all members for use.
