Just noticing these tags are listed under "Invalid" in posts. Don't see anything in the edit history which would explain this.

Edit - aaaand they're working fine now. Neat!

They don't appear to be on my end, and the wiki still cites them as species. Could you take a screenshot or link the posts that have scalie in the invalid category?

It was a bug that happened while changing the category of another tag.

https://e621.net/tags?commit=Search&search%5Bhide_empty%5D=0&search%5Bname_matches%5D=%2Arear%2A_%28disambiguation%29&search%5Border%5D=date

I invalidated this tag and the others changed because of a bug related to whitespace characters. All fixed now

scalie is a species tag on my end, the colors for invalid and species are kinda similar so it could be that?

scalie
invalid_tag

Not sure what would be going on with rear_view though, that's a general tag on my end.

edit: nvm lol

Dang, thanks for the quick replies y'all! Issue's gone so editing the post to reflect that (I assume that's the proper etiquette?)
