god i not used this for so long , but i was browsing the steam store for new DLC and i found a bit big mistake on other DLC on steam.
https://store.steampowered.com/app/367680/RimWorld_Name_in_Game_Access/ this one in particular , when i click "Your name must follow the creative rewards guidelines." (the link who is http://rimworldgame.com/creative/guidelines/ ) i get error 404
when i visit https://rimworldgame.com/creative/index.php , website also looks archaic , but also misses the "name guidelines" , i guess someone forgot to edit the ether changed link into store or "that part of site not exists anymore"
