I've noticed this glitch from time to time going through older observations in the "Needs ID" category. An observation goes through the typical sequence of being ID'ed first to order/family/genus level, and then to species ultimately achieving enough consensus to get to Research Grade. However, if there is a higher-level taxon change that does not affect the species ID, a new higher-level ID is automatically added to the observation causing an apparent disagreement and loss of RG status. Here's a good example: https://www.inaturalist.org/observations/6257329
Of course, if I'm familiar enough with the species to confirm the ID, I'll simply agree with the previous species-level ID and it goes back to RG. But I'm sure there are a lot of older observations like this that hang out there for a long time until an expert comes across them. That makes sense if the taxon change affects the ID (e.g., 1 species split into 2 or more - which I know has been discussed in previous threads), but I'm wondering if there's a way to prevent the system from treating these higher-level swaps as if they were new, disagreeing IDs.
