"Something else"
Unearthed Arcana: Modern Magic. A surprising number of campaigns I've been in or have been invited to have been in modern day or futuristic settings. I asked a while back, last year I think, and I was told to leave a request in the gitHub. Somebody responded but nothing happened, and I didn't want to pursue it because I felt like it'd make me the asshole, since I obviously have nothing to contribute.
I found it odd that all of the other UAs from around the time were added, but not that one. I kept expecting it to make it but I realised it must have been skipped intentionally for one reason or another
