1) I get notified that an update is there when I try to login... a new version is downloaded, the app quits and then the app re-opens.
2) When the app re-opens I can't do anything (all the menus are grey), so I have to quit it.
3) When I re-open the app and try to login, the 'second part' of the update has to download. Once it has downloaded, I try to login and despite it being correct, the app will say 'your password is wrong'.
4) I quit the app and re-open it... now I can play the game.
Is this something the devs have thought about and put in the 'too hard, it's annoying but we wanna improve the game instead' basket, or is it something that only happens on some computers, which they may not be aware of?
