The way I see it, if youíre using wall rings to upgrade 10 100k walls, it still takes the full 10 wall rings instead of receiving a 9 ring discount for still being 1 million. Same rules apply for this scenario, you canít get your resources back, and the ring prices are NOT going to be changed. However, if wall rings and the discounts are really that much of a hassle to you, feel free to remove your gold pass and never use wall rings again.
