The Issue
After successfully starting my own fast food restaurant, I encountered a severe bug. As I ran out of the restaurant building into the outdoor area, I accidentally clicked on a nearby trash can with my mouse. This caused my character to hold the trash can while stepping outside. A prompt initially appeared asking whether to take or destroy it, but after clicking ‘Close’, I received an error message: “You cannot pick up an occupied object.” Now, while my character appears to hold nothing, all interaction functions are completely disabled—I cannot interact with anything, not even open the map.
What I Tried
Reloading previous save files failed to restore interactivity.
Conclusion
I suspect my save file is corrupted.
