Now that I have found the pepperflask shop (I wasn't expecting anyone not in the Pokemon tower would sell that or ashes...), the ashes shortage has calmed down. I don't think you should increase drop chances (it will just cause something else to be in short supply), but rather increase the drop quantity. If you change the gather system, I would advice against adding too much extra steps at each gathering, as a good part of the gameplay is already pressing C to get ingredients, then run until more can be gathered. 🧚🧚🧚
