I have a column of names reconciled to Wikidata. When I hover the mouse on a name, I get the item’s preview. However, there are names which show an error, even they are reconciled, and a clicking takes me to the Wikidata item.
Why is that?
I think it’s related to this problem/issue in the Wikidata/Wikibase reconciliation service (although the issue points to a similar problem occurring in a different place).
In any case, it’s a bug AFAIK.
Thanks, @Sandra. I’m doing a presentation of OpenRefine in three days time, and I was panicking already 
I know that I can say it’s a bug.
