The Dark Elves mount, the Dark Cold One has always been called that since the launch of WH2, the "Dark Cold One", to separate it from the regular Cold Ones used by the Lizardmen.

But in WH3, the mount is suddenly called just "Cold One". The desciption when hoovering over the mount still is the correct one about the Cold Ones from Naggaroth, but I do feel like the name could use a slight tweak again to distinguish between regular Cold Ones and the corrupted versions.

Note how the Dark Steed and Dark Pegasus still contain Dark in the names of the mount (not having been renamed to Steed or Pegasus). So I figure this should be an error.

PS. The Cold One Chariot might also deserve renaming to Dark Cold One Chariot?
