When you click the link buttons it links to https://www.curseforge.com/minecraft/mc-mods/mini-hud and not https://www.curseforge.com/minecraft/mc-mods/minihud

The CurseForge slug was for a short time mini-hud instead of minihud, because the page didn't let me save some other changes if I didn't change the slug. And then it wouldn't let me change it back because "it's already in use". But then some time later it did let me change it back to minihud. So that's where that discrepancy comes from.

So yes the link in the mod info needs to be updated back to the old slug, and I again forgot to do it yesterday for the new builds...
