Please remember that this is just a beta market made for testing purposes, not for winning servers or glory as you can do on live servers
I don´t completely agree with you, * Arci *. Yes, this is Beta, but as you wrote quite correctly, for InnoGames it is a Beta
market with game worlds quite similar to those on live markets, and not only a sterile test environment. Over the years, there was only one V2 Beta game world closed prematurely (the disastrous "Rise of Heroes"^^); all other game worlds were offered and felt like normal game worlds with a higher bug risk. And, most important: The buying and using of gold is offered and encouraged just as it is on live worlds.
You cannot blame the players for expecting the same simple acknowledgement of their efforts, and I think this could be done without much fuss. A note could be added to the Hall of Fame entry (or the Hall of Fame entry could be replaced by that notes) acknowledging the performance of ICHOR on Sandbox 3 as well as the performance of Phoenix Reborn and Domination Complex on Warrior World, and I even think the devs could find a way to grant the crowns to the profiles of the ICHOR players concerned if a list of accounts is provided.
It is not their fault that zz3 was not reset correctly when Sandbox 3 started (there were further problems related to that fact, e.g. Sandbox 3 started with the era of wonders already reached, allegedly...^^), and I can understand that the ICHOR leaders are taking a stand for their disappointed members.
