Need help on Swift

[Rama]

Currently trying to develop Swift Emulator, until I realised, when I enter a room, I place furniture's down, then I leave and come back to it, (emulator does not restart or anything like that) it all dissapears? (Disincluding the wallpaper and etc) Does anyone have a fix to this?

Try a different version of swift.
