What a hell? "Error A sub-game can't have sub-games." For example this game: https://www.speedrun.com/ea1

It's kinda logic.

Plus that would be a huge mess if sub-games can have sub-games and these sub-games can have sub-games too. Like there's no end.

Oooh. I see. Its options for moderators, so it make sense in this case. hehe

Oh, that shouldn't even be appearing in the sidebar for sub-games. Fixed.
