ZDoom

Maybe this isn't a bug, just something you guys jumped with all those releases

The TAG_FIST string on the language files don't redirect to what's in the language file;
In other words, don't matter what you put here, the fist (Brass Knuckles on language.enu) will be shown as "Fist".

The "error" comes from the [wiki=Classes:Fist]fist[/wiki] weapon itself; it uses "$FIST" as the tag instead of "$TAG_FIST".

Fixed in r3996.
