[2021] Bug do not get ring of nibelungen / Lungnibbel Ring

Hello Segelflugpilot just to confirm what has been said, this is not a bug but intentional. You will receive this quest when taking part in the World Fair Exhibitions.

The rewards are randomized and the Lungnibbel Ring that you can be rewarded with, is just one of the tier 8, ​'​​​​​​Mythical Artifacts' that you can get as part of this exhibition quest.
