I posted a question regarding the game Wayward. Since there was no tag for it, I added one and then wrote a tag wiki entry. It was approved (I still see the reputation gain from the accepted edit), but the tag wiki is still empty. See here.
When I browse history, I see my edit there: https://gaming.stackexchange.com/posts/161087/revisions
So I got the reputation from an accepted edit, it seems it is the most recent version on the tag wiki, but I can't figure out why isn't it displayed on the tag wiki page.
