I have the Creative Mode mod. I can't usually be bothered to specifically disable or enable the mod for each game, as the first thing it does when you start a game is ask whether you want to enable or disable (including permanently) for that game. But, even with it disabled for that game, I then came across a [Z] Adventure chest which granted me a recipe.
It was a Creative mode recipe. The amusing thing was that it was a Biter spawn, which I REALLY didn't want. But I guess it could have been something else potentially useful.

Would it be possible to get the Mod not to select Creative Mode recipes as discoverable technologies?
I admit this isn't the biggest issue in the world as you could always disable the mod at the game level...
