I was doing helltide in World Tier 3, later i change to tier 4, to see if I can handle it and noticed the cinders move with me, I even open a chest in tier 4 with the cinders from tier 3. I think this may be an exploit because you can farm much quicker in a lower tier and get the chest items from tier 4. If that is the case i would like to have removed the items i got in that testing. However if not, if it is not a bug or exploit, could you please confirm?
