The shiny new option of automatically using Create Food during travelling is greyed out for me, even though I can cast this spell after random encounters just fine with my level 6 Life domain Cleric (the one from pregen).
I've used a save from the patch right before the winter update. It did load and the only oddity with spells I've noticed is that the game had other spells prepared, not the ones I've prepared before the update. But even after manually changing prepared spells on a long rest and preparing Create Food, the option is still greyed out and traveling food counter doesn't increase other than from hunting.
