I am attempting to change the parent taxon of Epicopeiidae but do not have the option when I try to edit that page. Most of the fields are greyed out and not editable, but the taxon is not locked. There is also an error message at the top of the page that reads:
I’m seeing that on any taxon with a lot of observations (>200k?). Not sure why it would show up on this one though. Might need to be reindexed with a Wikipedia link removal or just by saving?
