As of last week my best TCI is showing 'No TCI' with the following reason being displayed in the user's profile page:
It is not possible to generate TCIs with this account, either because it doesn't have enough breadth in ratings, or by special request.
I know he didn't disable it by special request, and he can still see my TCI, so I'm wondering what's going on. Could it be because his lowest tier is T2 instead of T1?
How many different tiers does he/she have? Because I can see that you have only 4, if your TCI also doesn't have many it might cause all kinds of problems.
