Arkadia is no better or worse than any other pp. Arkadia have bugs, Calypso have bugs, all planet partners have bugs. Don't fool yourself believing otherwise. And i heard that the Treasure Hunting system are ready since a long time, but Arkadia are not ready with it own content and have not implement it yet. So, Arkadia is not better or worse than any other planet. They all to a good job, but no one is perfect.
