DON'T PLAY. With new bugged release a treasury that introduced pay for rewards mechanic, it becomes shambolic game.. Since December every release of the game is released with many new bugs and fake apologies. If u software developer, this game is excellent resource to see in practice consequences of poor software development, testing code in production instead of listen feedback to QA and learn about new predatory practices to drain money from fans of the game. It is depressing game.
