Please allow for old seals to be exchanged for new ones as each time we have been saving seals for a specific item a new type of seal comes out and we are longer longer able to aquire the item we were saving for. This equates to putting money in bank savings account to find out the money is no longer valid because they changed the color or name of it.  Please find some way to either exchange old seals for news ones or be able to use new seals towards older rewards.
