Weeks and weeks have passed, and there is still no news on such an important issue. I think it's time to give up the game. Thank you to the ikariam community team.
What is the exact problem here? On all servers the process of moving to graveyard works as intended from what I know and see in my own accounts, the only exception is war servers where indeed the inactive accounts are not being removed at all for now.
So, I'd recommend to be more specific than just telling that the inactive players are not being removed at all at it's just not true. If this is only about war servers, then I believe it has been told and repeated dozens and dozens of times, and posting the same question again will just cause locking another thread.
