I believe this taxon swap should have been done at the genus level, not the species level. It has resulted in changing some research grade observations to needs ID, because any ID's at the genus level on these observations are now creating a genus-level disagreement.

Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
