This is not Asobo’s doing, it’s Microsoft’s doing. Microsoft pushed a update to Gaming Services, like DarkClown said, and that is what is causing the issue. The GS bug reported (UI Broken and Reset User Settings) obviously ties in pretty heavily with the sim and for some reason, forces the sim to behave in a strange way, resetting all previously saved settings & not communicating profile requests properly.
I’ve read on other forums that other games are having similar issues, where they’re reliant somewhat on Microsoft’s Xbox gaming servers and the Gaming Services. It turns out that it’s happened before, where gaming communities have had issues because of Gaming Services receiving a bugged patch.
Hopefully Microsoft should push out a hotfix patch for GS sometime Monday, as I’ve noticed that it can get patched 2-4 times a week.
