I have a similar problem, the game starts and then i have two errors if i let the game synchronize it just says me that it wont start because it had an error synchronizing with data of the game that i dont have,
then if i won't let the game synchronize and use a pre set the game start loading and then just load until a random number and stays there for hours until it closes by it self without any error to pop-up.
I've been looking for an awnser but i can't find anything to solve my problem.
Thanks for the time.
