For this query:
SELECT * WHERE { VALUES ?item { wd:Q48194 wd:Q470380 wd:Q470445 } . ?item wdt:P6885 wd:Q43266 . }
it should yield three results but there is only one. For instance, Q470380 does have this property and it is in RDF export, too.
Previously, both items had this property in WDQS, as demonstrated by this ListeriaBot list (rows "Přerov" and "Prostějov").
Their disappearance coincides with the data loss described in T228569.
