Although I’m not fully against the idea, I’m putting this under “bug reports” as I don’t think this is intended behavior.
Many species were split off from Unio crassus, a species included in the CV model. Each taxon split off of U. crassus is now included in the model as well:
(Suggestions for https://www.inaturalist.org/observations/25900561)
Some species in the Unio crassus complex (e.g. U. nanus) have only 1 observation and are still included in the model:
When one species is suggested, it also appears to suggest many more from the complex:
I presume the species are being suggested based off of the training data of U. crassus s.l.
Maybe another result of the delayed CV update?
