I don't know if your wiki is outdated or the the mods bugged. But when I spawn a custom NPC. Their menu is nothing like the way it describes in the wiki. How do I edit the NPC?.

You are probably looking at the wiki of the original Better Dungeons/Chocolate Quest mod (only available up MC 1.7.10).
This mod (Chocolate Quest Repoured, only available for MC 1.12.2) is rewrite of the original and also created by other people.

hmmm well from what I can tell the new wiki for this version of Chocolate Quest has some bugs too. Every time I try to go to the webpage I keep getting an error message saying "hmmm can't reach this page".

That’s not a bug, the ssl certificate is just outdated

However, maybe you use the wrong wiki url (there was a fandom one which we shut down), this is the correct URL: http://wiki.cq-repoured.net
