Dear Steeldragon,
i am playing the game with friends and sometimes stumbling over very sweet mods. Like this one. Added it, and the research menu shows its name on the Train research. But i believe i am not finding this item in my crafting menu in the particular save i am playing with my friends. On other saves i can find it.

Is this known behaviour of the game, or a Bug in the mod? Could i trigger a routine that somehow reevaluates the researched and unlocked recipes?
Please don't burn me if this doesnt belong here :)
