Semicolons (";") can be used as "or" and "otherwise", but could be confused as "and", "plus" and "even with one part enabled".

In this article, a semicolon is put in between "Game includes the Super Mario Mash-up pack" and "cross-platform play..." which would mislead people who don't find this deceptive into believing that Super Mario Mash-up Pack could be used on cross-platform multiplayer before finding out currently it isn't after the purchase.

Proof of the issue: Assuming this article and it's physical game (box / case), players could simply use the mash-up pack (including the skin and even the world included) on cross-platform multiplayer because there were no disclaimers. But as of Release 1.20.81 on Nintendo Switch, after the purchase, the Super Mario Mash-up Pack in the game do not allow cross-platform multiplayer (even if you "enabled" multiplayer from a world template in Create New World Screen) and disallowed those in skins from Super Mario Mash-up Pack from joining cross-platform multiplayer with both no official way of re-enabling that.

The solution is, if you weren't willing to make Super Mario Mash-up Pack to multiple platforms or even usable on cross-platform multiplayer in the future, add a disclaimer (like putting "(will forcefully disable cross-platform multiplayer but still can allow multiplayer with Nintendo Switch in Nintendo Switch Online / LAN mode with others)", or "#" after "Game includes the Super Mario Mash-up pack" and "# indicates that the content is only (available to specific platform and only) usable on multiplayer of same platform and will have cross-platform multiplayer forcefully disabled... " on the footer of article) to match the current time being and reduce confusion. Otherwise if you believe it was a bug on the game itself, just make that mash-up pack be usable for cross-platform multiplayer and better, make that mash-up pack to multiple platforms of Marketplace with Marketplace staffs (and Nintendo (licensee)) (and so to change the semicolon (";") to comma (",")) to make the claim no longer deceptive.
