It appears that @admin@lemmyrs.org has been busy at his job recently and hasn't had much spare time. He also ran into some issues upgrading to 0.18.1.

I don't this it's necessary to desticky this just yet, as it is of paramount importance to get smaller instances up and running at this stage. These comments and the posts on the server itself explain the situation well enough. If he's still on 0.17.4 in a few weeks then I would probably agree with you, and I appreciate you bringing it to people's attention.
