seems like everything that isn't "kbin.social" shows a url instead of the shortened mention.
if you mention a magazine that is on kbin.social, it doesn't even work/show, if you mention a fedia or kglitch magazine at "kbin.social" it shows a short mention on my side but a full url on your side.. it is broken :,D
left kbin, right fedia, another kbin based instance - so if i post a kbin magazine on kbin it doesnt gonna show, while fedia magazines etc do show, but as a full url vice versa :) really chaotic
@Ferk
it might be the /kbin core, not your site you're on.
if you mention someone at your instance here i also prob would see a "full url" (as long it's not the same instance we are on, yes even if it's kbin based)
linking magazines is even more broken.
if i link a kbin social magazine, its not even gonna show, if i do mention a magazine on another instance here on kbin.social it does shorten and link to it, while the ppl over there just see the "full url" of my mention vice versa :,D
