I recently started moderating r/cryptoadoption and posting adoption related things there... now it's gone

First of all: Please do not witch hunt reddit admins or pile on elsewhere. I've posted to r/bugs and r/help and we'll see how it goes. I'm just here in r/btc to ask the community for help figuring out what happened, and moving forward. Here's the story.

I was recently granted moderator privileges for r/cryptoadoption:

https:/np.reddit.com/r/redditrequest/comments/nzqwod/requesting_rcryptoadoption/

Today, r/cryptoadoption appears to have completely disappeared, and I'm now apparently a mod of r/a:t5_dwu6s/, which has had all of r/cryptoadoption's post history copied over.

Is anyone aware of anything like this happening before? If it's a bug, it's a pretty wild one, I guess.

I wonder what the chances of getting it back are... if I go to r/cryptoadoption and try to start it as a new subreddit, it says it's taken, even though I got there from the page saying that it didn't exist.
