This happened again today, but with a topic title that changed in the forum before being updated on the iNat dashboard.
https://forum.inaturalist.org/t/catholics-wanted became
https://forum.inaturalist.org/t/documenting-biodiversity-on-catholic-lands/20248
Not sure if this is related to what happened before, but there also is no number after the previous title. It’s all caught up now though.
