I have about 200 epic tokens so I was thinking about turning those in for hearts of wood before U20. Will those hearts work after U20? Will they be converted to the new item?
Also, I purchased a few lesser hearts from the store when they were on sale. Will those continue to work and/or be converted?
One simple solution is to provide a stone of change recipe for the old hearts and then you can continue allowing hearts to be acquired from the twelve.
Thank you,
