I feel like that that treats submitting individual connections like the wrong way to play. Obviously there's nothing wrong with finding everything first and putting them after but the game isn't designed as though doing otherwise is playing it wrong
Its just feels bad on such an explicit and clear connection, on a different day that could be a right answer and I don't feel like I was playing incorrectly by submitting it before finding every other category
I dunno, maybe I'm being unreasonable
Edit: if the red herring overlaps with every group like here so you don't have to find everything to know it's the red herring, that at least makes it feel a bit less unfair. I still don't really feel like I'm playing the game wrong by submitting a clear connection though. I guess the designers disagree.
