I'm not sure, but maybe from the last update my game won't load again after my screen is off and i turn it on again. I need to close the app and open it again. What could be the problem?
And it also loads twice every time I start it and download contents.
Do you have an apps-management app on your device? They sometimes cause such issues like that because they cache and flush the downloaded data every time.
No, I don't have any app like that.
Do you have any other idea?
I would reinstall it, but i'm afraid of to loose all of my standings (I'm logged on with Facebook, does it save my datas to cloud or not?).
Thanks for your answer!
As long as you are logged into Facebook and you play online, your city is saved. Depending on the last time it was synchronized before the issue appeared you could potentially lose a little bit of progress, but since you updated the game not long ago you shouldn't lose anything. Reinstalling is definitely worth trying because it could simply be that the update is corrupted.
