Run "patch-remove_unique_ref_indices.sql" then phase 1 of "Segregate Reference objects by source wiki." on officewiki.
I checked flow_wiki_ref and flow_ext_ref in production (not all the other tables so far) to see if there are any other discrepancies, which is how I noticed

```
This is presumably because officewiki was enabled after phase 1 was originally run in https://gerrit.wikimedia.org/r/#/c/136280 , this was overlooked, and officewiki is private (the only private wiki to currently use Flow)
