The game window reloads much more often than before. Sometimes it says 'the client lost connection etc', but until I press 'ok' it doesn't reload, and often I just have to wait a couple of seconds, after that the connection is reestablished and the game goes on without need of reloading. But many times it reloads the page without prompting anything, often after I won a battle, conquered a town or some gold site. I don't think these reloads are necessary, they really slow down everything if you (like me) don't have a very good connection.
It also happens often after I change the fight order.
