As a result of taxon swap 42539, observation 4176663 went from the genus level to the family level (“Some or all of the identifications affected by this split may have been replaced with identifications of Picidae. This happens when we can’t automatically assign an identification to one of the output taxa.”)
Because the observation had a “No, it’s as good as it can be” vote for the “Based on the evidence, can the Community Taxon still be confirmed or improved?” DQA question and such observations are marked casual when the community ID is family-level or higher, the observation was thus made casual, which seems like an unintended consequence. Perhaps it would be more appropriate to, in such cases, reset any existing votes for that DQA question and notify the previous voters that their votes need to be re-evaluated and potentially recast.
