There was a strange notice saying “added-curator.” Here's a photo:

How I got here:
I was using Scratch. I clicked Wiki Wednsday on the homepage. This appeared.

Notes:

• I did not post on the topic
  
• The URL was basic, no tags
  
• I could not recreate it
  

It was probably DjangoBB’s code being crazy. It was programmed(to my knowledge) in Python 1 or 2, and is way out of support

Sorry, if this is a bad explanation, but basically there are notices for actions, and the studios used to have one for curators, but it was removed when it was converted to 3.0 last year, so now it does this instead.
