Hi. As far as I can tell, none of my posts or comments from here are reaching kbin.social. I first noticed this about 3 days ago, trying to post comments to !fanfiction@kbin.social from here.
What's strange is that lemm.ee and lemmy.world seem to be federating perfectly fine, as do lemmy.world and kbin.social. This post I just made from lemmy.world is visible on both lemm.ee and kbin.social, but this post I made from lemm.ee yesterday only shows up on lemmy.world, not kbin.social. Both lemmy.world and lemm.ee are on version 0.18.1 right now, so I doubt it's related to the 0.18.0 Kbin-Lemmy federation issues. I'm also assuming the two instances are not intentionally defederated.
I can provide more details if needed. For now, I'm considering making an account on kbin.social to manually bring over some of the affected posts/comments. Either that, or reposting the content through my lemmy.world account.
Edit: made a kbin.social account. Seems like lemm.ee can view kbin.social comments, just not the other way around. As nice as the threadiverse is, it seems like there are still quite a few technical headaches to deal with at this point in time...
Oddly enough, I can't post any comments to kbin.social from lemmy.world either... even though there's clearly a bunch of recent posts on !kirby@lemmy.world posted from lemmy.world that are visible on kbin.social.
