If you don't know what is this, please see the first post where I explain everything, the comment with most upvotes gets the spot! ~(failed system, I know, sorry T ,T)~
I spent too long trying to figure out why the link to the previous post was not working. Turns out, the front end I use with my instance automatically overrides link so I see other instance's posts from my instance, but you're using a front end too and linked to that so it kinda shat itself lol
