I just realized a strange error after application of #10632.
Viewing Kirillov-Reshetikhin crystals themselves works fine.
However, viewing their tensor products is broken after the application
of the patch. Without the patch, this is fine. I am not quite sure,
where this error comes from.
Cheers,
Anne
