So, my friend has just called me this morning that all his save data was deleted. He told me that he woke up, opened his app and he was logged out. He then logged in and was greeted with nothing. Both of his police stations were gone. He then created another account with the same email and built a fire station.
What is the cause of the deletion of his stations and all his progress? I want to know so I can see how I can resolve this.
Thanks.
