Long play makes game choke.
So I have noticed that if SE have been playing for a couple of hours the game will run slow and start to freeze at random times. It doesn’t matter if your game is full or empty. It happens regardless if the game has been going on for some time.
I have a solution that will fix it.
Exit your game. Then reboot SE by going to dashboard menu and then press start on game icon to quit game. Then restart the game. When you then reload your game then the game will run perfectly again.
It is not a big problem. But I have noticed it will happen when playing for a few hours. And it happens regardless if your game is complex or total new start. A total reboot of the game fixes it.
