Kbin does odd things with links and communities, so I think part of the problem is it has mangled or added some unexpected links when you’ve written the post. However, some of your links in the original post work for me on Lemmy (!freegames is fine), so you might want to compare them.
I’m not sure why Lemmy uses an exclamation mark for communities when everywhere else uses an @. It would be a lot easier if it used @ then it’s universal for Kbin, Mastodon, Lemmy.
The new communities group suggests to use the format I’ve used in my previous posts (basically /c/community@instance) - this won’t work on Kbin because it uses /m/. It’s better to use @ there as you said.
Firelord is an old one but gorgeous. Chicory is pretty, in a colouring book sort of way. Child of Light and Forgotton Anne have fairly similar aesthetics but are both lovely.
