Hi Matej,
Is there a way to track this type of edit? It doesn't look problematic in the diff, but further down, https://www.wikidata.org/w/index.php?title=Q184169&diff=805632017&oldid=799562163#P570 one notes that there are 5 refs supporting the current date. Ideally type of change should be monitored unless the reference is "imported from Wikimedia".
