1840 census locations are STILL botched
I had this written up in the legacy channel here: https://community.familysearch.org/s/idea/0874V000000sih6QAA/detail
which includes several examples. It's not going to copy cleanly, so please go there for the details.
In short, it looks like for 1840 census records, if the state wasn't included in the original index, the "event place" doesn't link to the correct location. This means it don't appear in searches if the correct location is included in the search, and when linking the record, the wrong location is included in the info.
This definitely WAS working and broke earlier this year. If I had to guess, I'd say whatever code tries to standardize the location stopped taking into account the location specified by the census volume itself.
This record page says it's for it's for Waterford, Wahkiakum, Washington, United States, because "original" event place is Waterford, Washington. A search for Daniel Robert residing in Ohio won't find this. But if you view the image, it knows shows the correct location for the catalog breadcrumb of Ohio > Washington > Waterford Township: https://www.familysearch.org/ark:/61903/3:1:33SQ-GYY1-9NB7
