If the Make button is greyed out but you still have Power to make new Recipes or Crafts, then you’ve probably added multiple items in your queue and you don’t have the necessary ingredients to make all of them.
To use all your Power again, all you have to do is hover with your mouse cursor over the queued items and click the “X” that appears. This will remove them from the queue.
Make sure to check both the Kitchen and Shack.
