On PBE, it seems that if you have a bugged item, you will see the following message:
Dearest [Champ Name].
We seem to have found ourselves a small bug with this item. Please consider recalling and purchasing an upgrade in the shop as we do believe that it would be most beneficial to your further success.
Sincerely Riot Games
it was shown in PBE pre-season dev stream yesterday
