Hey there you probably scared that you lost everything do you?
Fear not my friend im here to help you!
First and foremost you Have yo know this tutorial apply only and only on PC as for Xbox the method is kinda different but the idea is the same!
Requirements are offline permission MUST be on! Otherwise it wont work!
We start off by going to this location
C:/users/yourPCName/appdata/local/packages/microsoft.sunrisebasegame_Randomletters**/systemappdata/wgs/
Wipe out everything there and leave the file named “t”
And then would suggest yet not required a system restart open forza and let it sync and download your latest save file from the cloud keep in mind that might take several mins up to an hour if not more!
Thats it!
Cause of the issue? File courreption it could be anything as force shutdown/crashes while the data are been updated and syncing to the cloud etc…
------------------------__________________________----------------------
Now for the Xbox
Go to settings and check out check it in general or account somewhere where it atore your data
Once you find the account savings or something like that go ahead and delete local save file for your games
Dont worry your gold as long as there is the word Local! It means the files which are stored in the XBOX which could be outdated! Doing so will force syncing to the cloud same thing as PC.
There you go! If i helped you please leave a comment
