Seems like discussion of the version numbers is getting mixed up then. I just logged out of Liftoff and logged back in with zero issues on my instance running 0.18.5.

As you can see in the GitHub link I posted in my previous comment, there’s only one major commit difference between 0.18.4 and .5, which fixes deletions not propagating correctly through Federation when an admin deletes a post who wasn’t a mod of the community (but still an admin of the community’s main instance) in question.
